Aspect ratios describe the shape of your video frame by comparing its width with its height. Choosing that shape affects what you can show, where text fits and how much of your original footage survives a crop. This guide covers 12 common aspect ratios, where you will use them and how to plan a shoot that needs more than one version.
| What are aspect ratios? An aspect ratio is a frame’s width compared with its height. Use 16:9 for conventional widescreen video and 9:16 for full-screen vertical social video. Cinema commonly uses 1.85:1 or 2.39:1. Choose the delivery shape before filming so important action and text stay inside the finished frame. |
Aspect ratios express the relationship between an image’s width and height rather than its total number of pixels. In 16:9, the image is 16 units wide for every nine units high. Those units can describe a small preview or a large projection.
Resolution tells you how many pixels make up that image. A 1920 × 1080 video has a 16:9 shape because both dimensions reduce to that ratio. A 1080 × 1350 video has a 4:5 shape. The dimensions are a resolution. The reduced relationship is the aspect ratio.
Two images can contain the same total number of pixels but distribute them across different widths and heights. Shape and detail are separate decisions. There is one technical exception to keep in mind: footage with non-square pixels needs its pixel shape interpreted correctly. Modern web delivery normally uses square pixels.
People asking “what are aspect ratios” usually need a delivery decision. Start with the screen and placement. Then choose the resolution required for that frame.
Most of our shoots now end up in more than one shape. A client asks for a website video, then mentions a week later that they also want Reels. If we only framed for 16:9, the vertical version loses half the people in the shot. So we ask for the delivery list before we plan a single setup. I put the vertical and square guides on the monitor and check every take against them. It adds a few minutes on set. It saves hours in the edit and a reshoot nobody wants to pay for.
These different aspect ratios give you a practical starting point for framing and delivery.
| Aspect ratio | Shape | Common pixel size or illustration | Where it is used |
|---|---|---|---|
| 16:9 | Wide | 1920 × 1080 | TV, YouTube, websites |
| 9:16 | Tall | 1080 × 1920 | Vertical social video |
| 1:1 | Square | 1080 × 1080 | Feed posts, carousels |
| 4:5 | Portrait | 1080 × 1350 | Social feeds |
| 4:3 | Moderately wide | 1440 × 1080 | Archive-style video, presentations |
| 2.39:1 | Very wide | 2048 × 858, approximately | Scope cinema delivery |
| 1.85:1 | Wide | 1998 × 1080, approximately | Flat cinema delivery |
| 21:9 | Ultrawide | 2560 × 1080, approximately | Monitors, custom banners |
| 2:1 | Wide | 3840 × 1920 | Streaming-style presentation |
| 1.37:1 | Near square | 1480 × 1080, approximately | Academy-style framing |
| 1.43:1 | Tall cinema frame | 1430 × 1000, illustration only | Selected IMAX presentations |
| 3:2 | Moderately wide | 3000 × 2000 | Photography, open-gate capture |
For most business projects, start by discussing 16:9, 9:16 and 1:1. These cover familiar widescreen, vertical and square placements. The table does not list all aspect ratios that exist. Some pixel sizes illustrate shape rather than prescribe a delivery master. Cinema masters follow the distributor’s specifications. Do not export an unusual resolution just because its proportions match a theatrical format.
Choose the ratio that fits the main viewing placement and the composition your message needs.
We would rather decide the delivery list while planning social media video production than discover it after the shoot. That decision changes camera position, background choice and where a person stands. If the same campaign needs a group shot and a vertical close-up, schedule both. A few deliberate variations can protect the edit better than recording everything wide and hoping the crop works.
The following video aspect ratios serve different framing needs, even when the subject stays the same.
16:9 is the familiar widescreen shape used for HD and UHD video. It gives a speaker enough room for a workplace background or a graphic beside them. It also fits conventional YouTube players and widescreen televisions well.
For corporate video production, this is often a sensible master when the main destination is a website, presentation or long-form video channel. Plan a separate vertical composition if the campaign also needs phone-first placements.
Is it better than 4:3? It is better suited to modern widescreen delivery. The narrower frame can still be the right creative choice. Neither ratio makes the footage sharper by itself. Comparing 16:9 aspect ratios with other shapes is a composition decision before it is a quality decision.
Best uses
Use it for website videos, conventional YouTube uploads and widescreen presentations. Choose another shape when the placement or story calls for it.
9:16 is a tall frame designed to use a vertically held phone screen. It works well for a person addressing the camera, a close product demonstration or a sequence built around one clear action.
The difficulty is fitting sideways movement into a narrow picture. A person crossing a workshop can leave the crop before completing the action. Plan their position and camera movement for the vertical version. Keep captions and essential product details away from interface areas.
Understanding what is TikTok helps explain why a video should feel composed for a phone rather than squeezed out of a television frame. Reels, Shorts and Stories also use vertical viewing, though each placement has its own requirements.
Best uses
Use it for full-screen social placements and short presenter videos. Shoot a dedicated version when the main action does not survive a centre crop.
1:1 gives equal space to width and height. The square shape can hold a face, a product and a short line of text without making the layout feel strongly horizontal or vertical.
It remains useful for feed posts and video within carousels. A square layout also gives a designer a predictable frame when still images and video appear together. The key is to compose inside that square from the beginning. A wide group interview rarely becomes a good square video through cropping alone.
Keep the main action close enough to read on a phone. Avoid placing essential information in the corners just because the layout looks balanced on a desktop monitor. Review the finished export at the size people will actually see.
Best uses
Use it for social feed assets and coordinated carousel content. It also suits short product loops with a central subject.
4:5 is a portrait frame that is taller than a square without being as narrow as 9:16. It gives you more vertical room for a person, a product or stacked information in a social feed.
This shape can keep more of a seated person’s body visible while leaving space for captions. It can also show a tabletop product from above without forcing everything into a tall strip. Confirm the placement before exporting because feed behaviour and available ad formats vary.
When comparing 4:5 aspect ratios with square delivery, look at the whole design. Extra height only helps if you use it well. Do not fill that space with small text that requires the viewer to stop and read a paragraph.
Best uses
Use it for portrait feed content on platforms that support it. It suits customer stories, product features and caption-led clips.
4:3 is the narrower television shape associated with older broadcasts and many archive recordings. It can create an intentional period feel or keep attention on a face with less space at the sides.
Do not assume every old film used this exact ratio. Film aspect ratios have changed across production and exhibition systems. Treat 4:3 as a specific shape rather than a label for everything made before widescreen.
For archive material, preserving the original frame often matters more than filling a modern screen. Stretching it makes people and objects look wider. Cropping the top and bottom can remove useful information. Pillarboxing places empty space at the sides and keeps the original image intact.
Best uses
Use it for archive presentation or a deliberate retro treatment. Compare 4:3 aspect ratios against the final screen before choosing them for a presentation.
2.39:1 is a very wide cinema shape associated with scope presentation. It gives a composition room for several people, architecture or a strong relationship between foreground and background.
The frame does not prove that a production used anamorphic lenses. Those lenses compress the image during capture. A spherical-lens image can also be cropped to a wide shape. The ratio and the lens characteristics are separate choices.
You will encounter 2.35:1 and 2.40:1 in discussions of movie aspect ratios. They are related labels with historical and practical differences rather than exact mathematical equivalents. Confirm the required deliverable instead of treating every scope label as interchangeable.
Best uses
Use it when the story benefits from width and the delivery supports it. Avoid using black bars as a substitute for purposeful framing.
1.85:1 is a common theatrical widescreen ratio with more height than a scope frame. It sits close to 16:9 but is not identical.
That difference matters when text, faces or movement sit near the top or bottom of the image. A small crop can still cut through a title. Work with the distributor’s framing and delivery requirements when preparing a cinema version.
Among cinema aspect ratios, this shape offers a useful balance between environment and people. It gives a standing person more breathing room than a very wide frame while still allowing a horizontal composition. Do not assume a standard web export is a finished cinema master simply because it looks similar on your monitor.
Best uses
Use it for projects planned around flat theatrical presentation. It can also be a creative widescreen choice for a film delivered online.
21:9 is a broad ultrawide label used around monitors and panoramic content. Products described this way do not always use dimensions that reduce to exactly 21:9.
A website banner needs its own layout checks. The same video can appear differently when a responsive page crops it to fill a container. A face positioned near the edge on desktop may disappear on a phone.
Get the actual display dimensions and the website’s crop behaviour before filming. Keep important action within the region that remains visible across screen sizes. If the banner needs a separate mobile version, plan one rather than making the desktop frame carry every task.
Best uses
Use it for custom display installations or panoramic web layouts. Confirm the real pixel dimensions before delivering the final asset.
2:1 is a widescreen shape with a width exactly twice its height. It offers more horizontal space than 16:9 without becoming as wide as a scope frame.
You may see it associated with the Univisium proposal and with streaming-era productions. Its usefulness comes from the composition rather than the label. It can hold a conversation between people while leaving enough height to read their surroundings.
If the final player is 16:9, expect some unused space above and below the image unless the player adapts. Do not crop a finished 16:9 video to 2:1 without checking every shot. Headroom, subtitles and logos can all be affected by a seemingly modest change.
Best uses
Use it for films and brand stories with a planned wide composition. Keep a separate delivery plan for vertical cutdowns.
1.37:1 is the near-square shape associated with the Academy sound-film standard. It resembles 4:3 but is slightly wider.
This frame can make a face or a room feel contained. It also changes how people move through a scene. A composition that relies on several subjects spread across the frame will need rethinking.
When using aspect ratios in film to suggest a period, make the other visual choices support that intention. Lighting, production design and camera movement do more than the frame alone. For archive restoration, preserve the source’s intended presentation rather than forcing it into whichever near-square preset is easiest to select.
Best uses
Use it for period treatments or films that benefit from a contained composition. Check the exact source ratio when working with archive material.
1.43:1 is the tall expanded frame used in selected IMAX presentations. It should not be treated as the shape of every IMAX screening.
The capture format, projection system and available screen determine what an audience actually sees. Some IMAX presentations use a different frame. A web upload with a 1.43:1 crop does not become an IMAX production.
For a producer, the practical lesson is to plan the intended exhibition format before capture. Extra image area above and below the subject changes composition. It can reveal set edges, lighting or other details that would sit outside a wider frame. A multi-format production needs deliberate framing guides and delivery supervision.
Best uses
Use it only when the production and exhibition plan calls for it. Follow the technical requirements of the intended release.
3:2 is a moderately wide shape strongly associated with still photography. Some cameras also offer a taller sensor recording area that gives editors more options for video reframing.
Capture shape and delivery shape do not have to match. A camera may record a 3:2 image so the editor can create both wide and vertical versions. Check the camera’s actual recording mode before relying on that option.
The benefit is room to move the crop. The limit is resolution and composition. A wider group cannot always fit inside a narrow vertical window simply because there are more pixels available. When discussing 3:2 aspect ratios, separate the source recording from the finished file your audience will watch.
Best uses
Use it for flexible capture where the camera supports it. Deliver the version that fits the final placement.
Platform choice gives you a delivery starting point rather than a universal rule for every placement.
| Platform | Recommended aspect ratio | Notes |
|---|---|---|
| YouTube | 16:9 for conventional widescreen uploads | Other shapes can display in an adapting player |
| YouTube Shorts | 9:16 for full-screen vertical viewing | Square uploads can also qualify as Shorts |
| TikTok | 9:16 as a practical phone-first master | Check the specific organic or ad placement |
| Instagram Reels | 9:16 as a practical full-screen master | Preview covers, captions and interface overlap |
| Instagram feed | 4:5 or 1:1 as practical options | Confirm the current post or ad format |
| Facebook feed | 4:5 or 1:1 as practical options | Requirements vary by placement |
| LinkedIn feed | 1:1, 4:5 or 16:9 according to composition | Confirm the intended post or campaign placement |
| TV broadcast | Commonly 16:9 | Obtain the broadcaster’s delivery specification |
| Cinema | Commonly 1.85:1 or 2.39:1 | Obtain the distributor’s master specification |
These are planning recommendations, not a complete specification sheet or a promise that every placement accepts the same files. TV aspect ratios and broadcast delivery also involve technical requirements beyond frame shape. Social platforms change their interfaces and available formats. Before export, check the destination’s current upload guidance and preview the actual placement. A file that uploads successfully can still lose a title to a crop or interface overlay.
Shoot for multiple ratios by protecting the important action inside every planned delivery frame.
Add framing guides to the camera monitor before the first take. Use them to check the person’s face, hands and any product interaction. Centring the subject helps in some shots, but a centred face does not protect a second person standing at the edge.
Record at a suitable resolution when the delivery plan needs cropping. More pixels provide flexibility. They do not restore missing action outside the camera frame. Review types of camera shots with the final crops in mind. A close-up may need little adjustment while a wide team shot needs a separate setup.
Leave enough space for different caption layouts. Add graphics in the edit for each version instead of baking a widescreen title into the source recording. Plan dedicated vertical takes when a demonstration stretches across a table.
Much conventional drone videography is recorded wide and cropped for other placements, although some systems offer vertical capture. Check the aircraft and recording mode. A sweeping wide aerial may lose its subject in a narrow crop.
Finally, make the delivery list part of the video editing services brief. Each ratio needs its own framing review. Watch every export rather than approving the wide master and assuming the rest will work.
16:9 is the conventional starting point for widescreen video on televisions, websites and long-form YouTube channels. It is not the default for every placement. Full-screen vertical social content commonly uses 9:16. Choose according to where the audience will watch and whether the composition needs space beside the subject. Confirm additional delivery versions before filming rather than choosing only at export.
1920 × 1080 has a 16:9 aspect ratio when displayed with square pixels. Divide both dimensions by 120 to reduce them to 16 and nine. The pixel dimensions describe resolution while the ratio describes shape. A larger 3840 × 2160 image has the same proportions but contains more pixels. It does not show a wider composition simply because the resolution is higher.
16:9 is generally the better fit for modern widescreen delivery while 4:3 suits archive material or a deliberate creative treatment. Quality comes from capture, lighting, sound and the finished edit. Frame shape alone does not determine quality. Preserve an archive image’s intended shape unless there is a clear editorial reason to crop it. Stretching it to fill a widescreen display distorts the subject.
1080 × 1350 is a pixel resolution with a 4:5 aspect ratio. Reducing both dimensions by 270 gives four and five. It is a portrait frame that is taller than a square and wider than a 9:16 vertical composition. Check that the destination supports the chosen resolution and preview how the post appears in its feed or ad placement before publishing.
Movies use several aspect ratios, with 1.85:1 and 2.39:1 common in theatrical presentation. Some films use narrower frames or change shape between sequences. Selected IMAX presentations can use a taller expanded frame. Follow the intended release specification rather than assuming every film needs scope framing. The composition should serve the story and survive the formats in which audiences will see it.
Use 9:16 for a full-screen vertical placement and consider 4:5 or 1:1 for supported feed placements. The specific platform, post type and ad placement decide the final requirements. Plan captions and important action inside the visible area. If one campaign needs several shapes, approve those versions in the brief so the shoot includes the compositions needed for each export.
You can change the aspect ratio by cropping, adding borders or rebuilding the layout, but each approach has limits. Cropping removes image area. Borders preserve the original composition but leave unused space. Reframing may require separate graphics and captions. When planning commercial video production, agree on the delivery shapes before filming so the footage supports those changes cleanly.
Choose the delivery frame before you choose the final composition. Write every required version into the brief and test the difficult shots through those framing guides. A clean vertical close-up and a purposeful wide shot are often more useful than one compromised master. The right ratio is the one that keeps your subject, message and essential text clear in the place the audience will actually watch.
