Social media image sizes: 4:5 in the feed and 9:16 in Reels
Prepare versions that respect each placement’s crop and keep your product, message, and call to action visible.

Meta recommends 4:5 and 1440 × 1800 px for Facebook and Instagram feed, plus 9:16 and at least 1440 × 2560 px for Stories and Reels. But size alone is not enough: you also need to protect the crop, priority content, and the versions each placement actually displays.
What separates an image format from its pixel dimensions?
Format defines the canvas shape, while pixels define its specific dimensions. A 1:1 asset and a 16:9 asset may both have good quality, yet they arrange the photo, copy, and call to action differently. That distinction determines which composition your campaign needs.
An aspect ratio describes the proportion between width and height, not a fixed measurement. As MDN Web Docs explains, 1:1 and 16:9 describe formats; 1080 × 1350 describes file dimensions. Separating those decisions keeps you from copying a number without considering the room your message needs.
| Decision | Describes | Example |
|---|---|---|
| Format | Proportion | 1:1 or 16:9 |
| Size | Pixels | 1080 × 1350 |
| Composition | Visual order | Product and offer |
For a product ad, composition starts before export settings do. The master photo can stay the same, but a full-screen vertical version often needs more space above and below than a feed composition. The main benefit and action belong where people can still see them.
Which formats should a campaign use for feed, Stories, and Reels?
Meta’s Ads Guide distinguishes between two canvases: 4:5 for feed and 9:16 for Stories and Reels. The Meta Ads Guide provides that starting point before campaign surfaces are designed. For organic posts, the Instagram Help Center explains that the app uploads photos up to 1080 px wide with an aspect ratio between 1.91:1 and 3:4, and crops those that do not fit.
| Placement | Format | Recommended size |
|---|---|---|
| Facebook and Instagram feed | 4:5 | 1440 × 1800 px |
| Stories and Reels | 9:16 | 1440 × 2560 px |
| Instagram post | 1.91:1 to 3:4 | 1080 px wide |
| YouTube thumbnail | 16:9 | 3840 × 2160 px |
| Shorts thumbnail | 9:16 | 2160 × 3840 px |
YouTube even distinguishes between video thumbnails and Shorts thumbnails. Its help center recommends 3840 × 2160 px and 16:9 for videos, plus 2160 × 3840 px and 9:16 for Shorts; a 16:9 thumbnail for a vertical video can also be replaced with an automatic 4:5 thumbnail in Home, Explore, and Subscriptions. Check the YouTube thumbnail guide for the placement you need.
The right version keeps the central idea even when the arrangement changes. A store can use the same photo and offer across its campaign while repositioning the product and call to action for each crop. That adaptation also belongs in a digital marketing strategy built around how each ad is consumed.
How do I protect my message and product from cropping?
A safe area reserves the usable center of an asset for what cannot be lost. For Stories and Reels, Meta recommends leaving about the top 14%, bottom 35%, and 6% on each side clear of text, logos, and key elements so the call to action and profile icon do not cover them; at 1440 × 2560 px, that is about 358 px at the top, 896 at the bottom, and 86 on each side, according to its Ads Guide.
A channel guide can separate the full canvas from the area people always see. For its channel banner, YouTube recommends 2560 × 1440 px and publishes a 1235 × 338 px safe area for text and logos within the 2048 × 1152 px minimum upload size. The YouTube banner guide warns that some views and devices crop the rest.

Your message also has to survive against the background around it. Contrast, the difference in lightness between text and its background, keeps information readable when a photo changes scale. The W3C’s WCAG 2.2 sets a 4.5:1 minimum for normal text and 3:1 for large text, including words turned into images.
What can I reuse from one asset, and what should change by placement?
The main photo, benefit, and brand identity can remain consistent across versions. What changes is the order: the image may take more height, copy may break across different lines, and the action may move to stay inside the safe area. Reusing the entire file instead leaves the result at the mercy of cropping.
A restaurant promotion shows why an edge should never carry critical information. In the vertical asset, the price and date need room away from controls and account details; in feed, they can live in a more compact composition. The same logic applies to the landing pages we design, where image, offer, and action need to work across screen sizes.
How do I check a crop before publishing or launching an ad?
The useful check looks at every preview, not only the file open on a computer. Before publishing, review the asset in the placement where it will appear and with its real content. This reveals whether the product loses context, a word gets covered, or the action disappears.
- Confirm the campaign placements and objectives.
- Identify the product, benefit, and call to action.
- Place those elements inside the published safe area.
- Open the preview for every available format.
- Correct the crop and check it again before launch.
A preview should validate the complete message, not only that the file uploads. In a software tutorial, for example, the interface and title must still explain the video if YouTube changes the surface where it appears. That check turns dimensions into a communication decision, not an isolated list.

Where can I verify the current dimensions for each social network?
The reliable source is the official guide for the network and placement you plan to use. Specifications change by platform, post type, objective, and surface. An online table can start a conversation, but the official guide is consulted before a campaign is produced or promoted.
A versioning system makes it easier to respond when a specification changes. Keeping the master photo, copy, and compositions by format lets a campaign adjust without being rebuilt. That work can be coordinated through digital consulting when content, ads, and the website need the same underlying logic.
Frequently asked questions about image sizes
Common questions are resolved by separating the file, format, and placement. The answer is rarely a universal number because each surface presents the same campaign differently. These situations help you decide what to check before an asset reaches the public.
Does a 1080 × 1350 image work for every social network?
A 1080 × 1350 image is 4:5 and fits an Instagram post and the Facebook feed. But it is neither the 9:16 used for Stories and Reels nor the 16:9 used for a YouTube thumbnail. Before reusing it, confirm the required format and open the preview for the specific post or ad.
Why does an image that looks good in feed get cropped in a Story or Reel?
Feed, Stories, and Reels reserve different spaces for the asset and its controls. A composition that uses width well can lose elements when it fills a vertical screen. A vertical version is therefore more than stretching the asset: it reorders what matters inside the checked safe area.
How many versions of the same campaign should I produce?
Produce as many versions as the chosen placements need in terms of composition. A simple campaign may begin with one feed version and one full-screen vertical version; other surfaces may require another adaptation. The decision comes from the distribution plan, not a fixed number for every situation.
Can I use the same file for an organic post and an ad?
The same starting point can work, but placement and objective still need checking. An organic post and an ad may appear on different surfaces with their own crops or controls. Keeping the photo and message creates consistency; adjusting composition and reviewing the preview protects clarity.
Do you need your images to communicate fully in every placement?
At User Media, we design systems of assets that keep the message, product, and action visible where your campaign needs them. Let’s talk about your ads and content.
