Facebook Post Size 2026: Image, Video, Cover and Ad Sizes

Facebook does not force a crop ratio on a plain photo upload, but it publishes exact numbers for link-share previews, Page covers, and profile pictures, and it retired the separate video post format entirely in September 2025. Every number below comes from Meta's Help Center and Meta for Developers, fetched in September 2026.

If you also run an Instagram account, the companion guide to Instagram post sizes for 2026 covers feed photos, Reels, Stories, and a carousel rule most guides get wrong.

Feed Image Posts: No Forced Ratio, But Not No Rules

Facebook's own Share photos on Facebook help page walks through posting a photo directly to your feed and does not publish a required aspect ratio or pixel size, unlike Instagram. That does not make size irrelevant: an extreme ratio still gets letterboxed or heavily downscaled by Facebook's feed layout. For predictable results, a square (1:1) photo around 1080 x 1080 pixels displays cleanly across desktop and mobile.

Link-Share Images Are a Different Spec Entirely

When you paste a URL into a Facebook post instead of uploading a photo, the preview image comes from your page's Open Graph og:image tag, and this is where Meta does publish exact numbers. Per Images in Link Shares, the minimum allowed image dimension is 200 x 200 pixels, with a file size cap of 8 MB. For the best display on high-resolution devices, Meta recommends at least 1200 x 630 pixels, and states that "at the minimum, you should use images that are 600 x 315 pixels to display link page posts with larger images." Below 600 x 315, the preview still shows, just smaller. Meta also advises keeping the image close to a 1.91:1 aspect ratio "to display the full image in Feed without any cropping."

Video Posts and Reels: The September 2025 Change

This is the update most size guides have not caught up on. Meta's Create a reel on Facebook help page states: "Facebook has unified all video uploads under the Reels format. All videos posted to Facebook will be shared as reels, regardless of length or orientation." The Reels on Facebook page confirms there is no separate video post type anymore: every upload is a Reel, whatever its length or aspect ratio, except Stories and Live video. In practice, Facebook no longer enforces a size or ratio on video at all, though vertical 9:16 framing still fills a phone screen edge to edge with no letterboxing.

Stories

Facebook's Share a photo or video to your story page confirms a story is visible to your selected audience for 24 hours and can be seen across both Facebook and Messenger, but it does not publish an aspect ratio or pixel dimension. Since Stories use the same full-screen vertical player as Reels, vertical framing close to 9:16 is the practical target, the same guidance covered in more detail in the Instagram post sizes guide.

Cover Photo and Profile Picture for Pages

Meta's Facebook Page profile picture and cover photo dimensions page is the single most specific size page Facebook publishes, and the numbers differ by device:

• Profile picture: displays at 176 x 176 pixels on computers, 196 x 196 on smartphones, and 36 x 36 on most feature phones. It is cropped to a circle, and Meta recommends uploading 320 pixels wide and 320 pixels tall for the best quality.
• Cover photo, desktop: left-aligned with a full bleed and a 16:9 aspect ratio, at least 400 x 150 pixels, loading fastest as an sRGB JPG at 851 x 315 pixels under 100 KB.
• Cover photo, mobile: the same minimum size and fastest-loading file spec, but a 2.4:1 aspect ratio instead of 16:9, since more of the image is visible on a narrower mobile screen.
• Overlap: on mobile, the profile picture overlaps the cover photo by approximately 40 pixels.

Because desktop and mobile crop the same file to different ratios, keep your logo or subject centered rather than near an edge, where one device or the other will cut it off.

Group and Event Covers

Facebook documents a specific number for one of these, not the other. The group cover photo help page recommends 1,640 x 856 pixels (1.91:1) and warns about gray safe-zone areas in its own sizing diagram, since "group visitors may not see the entire image on a mobile device." The event cover photo help page covers only how to add or remove one and states you cannot resize it afterward; it publishes no recommended pixel size or ratio.

How Sizes Differ for Boosted Posts and Ads

A plain feed photo has no forced ratio, but once it becomes a boosted post or an ad, it can reach placements a direct upload never touches: Stories, Reels, the right column, Marketplace, Audience Network, each with its own crop and minimum-resolution requirements. Ads Manager will flag or crop an asset that does not fit. Check the exact numbers on the Meta ad specs hub before boosting, and preview vertical placements with the Safe Zone Checker.

Common Mistakes

• Assuming Facebook enforces a feed photo ratio the way Instagram does. It does not; only a link-share preview has a published ratio.
• Designing a cover photo for desktop only. The mobile crop is 2.4:1, wider than desktop's 16:9, so a logo safe on desktop can be cut off on a phone.
• Publishing a link image under 600 x 315 pixels, then wondering why the preview shows small instead of large.
• Treating "Facebook video specs" as fixed. Since September 2025, Facebook no longer enforces a length or aspect ratio on video; it is all Reels now.
• Reusing a group cover's exact crop for an event cover, when Facebook publishes no matching spec for events and will not let you resize it after adding it.

How Adship Keeps Every Placement Sized Right

Checking a different spec for a feed photo, a link preview, a two-device Page cover, and a boosted placement every time you post is not realistic by hand. Adship's Canvas generates ad creative already sized for the placement your campaign uses, and the free tools hub includes the Safe Zone Checker above plus the full Meta ad specs hub for exact ad dimensions.

Frequently Asked Questions

What size should a Facebook post image be?

For a direct photo upload, Facebook does not publish a required ratio; a square image around 1080 x 1080 pixels displays predictably. If you are sharing a link instead of uploading a photo, the preview image should be at least 1200 x 630 pixels at a 1.91:1 ratio to avoid a small or cropped preview.

Is a Facebook video post still different from a Facebook Reel?

No, not since September 2025. Meta's Help Center states that all videos posted to Facebook are now shared as Reels, regardless of length or orientation, with the exception of Stories and Live video, which remain separate formats.

What size should my Facebook Page cover photo be?

At least 400 x 150 pixels, loading fastest as an sRGB JPG at 851 x 315 pixels under 100 KB. The aspect ratio differs by device: 16:9 on desktop and 2.4:1 on mobile, so keep important content centered rather than near the edges.

What image size should I use when sharing a link on Facebook?

At least 1200 x 630 pixels for the best display on high-resolution devices, per Meta for Developers. The absolute minimum is 200 x 200 pixels, and below 600 x 315 pixels the preview still displays but noticeably smaller.

What's the recommended size for a Facebook group cover photo?

1,640 x 856 pixels, a 1.91:1 ratio. Meta's own sizing diagram warns that mobile visitors may not see content placed in the gray safe-zone areas at the edges of that image.

Does boosting a post change my image requirements?

It can. A boosted post or ad can be delivered into placements, such as Stories, Reels, or the right column, that a plain feed upload never uses, each with its own crop and resolution requirements. Check the Meta ad specs hub before boosting rather than assuming your organic crop carries over.
