Social Media Ad Sizes for 2026: The Complete Cheat Sheet

Three aspect ratios cover the vast majority of social media ad placements in 2026: 4:5 vertical for Meta and LinkedIn mobile feeds, which Meta now recommends at 1440 x 1800, 9:16 full vertical for Stories, Reels, TikTok and Shorts, recommended by Meta at 1440 x 2560, and 1:1 square at 1080 x 1080 for carousel cards and as a universal fallback. Beyond those, link ads run at 1200 x 628, and Pinterest prefers a 2:3 ratio at 1000 x 1500. Build to those and you will have native creative for almost any campaign.

One note if you are working from an older cheat sheet, including an earlier version of this one: the 1080-series numbers are not wrong and nothing built to them will be rejected. Meta simply raised its recommended resolutions, so 1440 on the short edge is the current target for its placements.

Below is the full breakdown by platform, the safe zones that keep your text from being covered by the interface, and the file rules that stop an upload from getting rejected.

Social media ad sizes at a glance

Facebook and Instagram ad sizes

Meta placements share the same core sizes because Facebook and Instagram run on the same ad system, and Meta raised its recommendations in 2026. Feed is 4:5 at a recommended 1440 x 1800, up from the familiar 1080 x 1350, and Stories and Reels are 9:16 at a recommended 1440 x 2560 rather than 1080 x 1920. The older files are still accepted, they are just below what the placement now renders at. The 4:5 vertical takes up more screen on mobile and generally earns more attention than a square, which is why Meta lists it as the recommended feed ratio. Single-image link ads that show a headline and description below the image use 1200 x 628 (1.91:1). Our Meta ad sizes and creative specs page carries the full per-placement breakdown.

On Stories and Reels, keep your logo, text, and any call to action inside the middle of the frame. Meta's published margins are the top 14 percent, the bottom 35 percent, and 6 percent of each side, and that bottom figure is much larger than the 20 percent most cheat sheets print, because the caption, sound attribution and call to action button all stack there. See Meta ad safe zones for the pixel math. Upload as JPG or PNG up to 30 MB.

TikTok ad sizes

TikTok is vertical-first, and every ad format targets 9:16 at 1080 x 1920 pixels. The catch is the safe zone: the caption, profile icon, and interaction buttons occupy the right side and bottom of the screen, so keep critical text and your product within the center of the canvas, roughly an 810 x 1290 area. In-feed ad text runs up to 100 characters. Creative that reads as a native post, shot or styled vertically, outperforms anything that looks like a repurposed horizontal banner.

LinkedIn ad sizes

LinkedIn single-image ads perform well at 1200 x 1200 (1:1) for the feed, and 1080 x 1350 (4:5) also works on mobile. Link-share ads that pull a preview card use 1200 x 627 (1.91:1). LinkedIn's audience skews to work hours and professional context, so the creative that converts there tends to be cleaner and more text-forward than the same offer on TikTok. Company page image uploads cap around 3 MB, so compress before you upload. A LinkedIn ad maker is the fastest way to get that B2B tone and the 1:1 and 1.91:1 slots filled from the same brief.

Pinterest ad sizes

Pinterest rewards tall creative. The platform's native ratio is 2:3 at 1000 x 1500 pixels, and taller pins take up more of the vertical grid. A 1:1 square at 1000 x 1000 still works for standard pins, and idea or video pins use the full 9:16 vertical. Pinterest allows larger files, up to about 20 MB, which gives you room for high-detail product imagery. Rather than cropping a square Meta ad into the grid, a Pinterest ad maker renders the 2:3 pin natively along with the title and description.

Google Display ad sizes

Google's Display Network is banner-based, not feed-based, so the sizes are different. Five sizes cover most inventory: 300 x 250 (medium rectangle), 728 x 90 (leaderboard), 320 x 50 (mobile banner), 160 x 600 (wide skyscraper), and 300 x 600 (half page). If you run responsive display ads, Google generates size variations from your uploaded assets, but shipping the core static sizes gives you more control over how the ad looks. We cover the full list in our guide to Google display ad sizes.

The three sizes that cover almost everything

If you only produce three crops, produce these: 1:1 (1080 x 1080), 4:5 (1080 x 1350), and 9:16 (1080 x 1920). Between them they cover feed placements across every major platform plus all the full-screen vertical surfaces. Add a 1200 x 628 link image and a 1000 x 1500 Pinterest pin and you have a complete cross-platform set. The reason most teams still ship inconsistent creative is not that they do not know the sizes, it is that resizing the same idea by hand for every one is slow.

That is the specific job a social media ad maker removes. Instead of exporting one image and cropping it five times, you describe the product once and get every placement size rendered together, with the subject and text kept inside each platform's safe zone. It also helps to watch how your creative and your competitors' ads actually appear once they are live, which is where a habit of monitoring your brand across social platforms pays off: you see which formats are running and how yours stacks up.

Frequently asked questions

What is the best all-purpose social media ad size?

1080 x 1080 pixels (1:1 square) is the safest single size, because it displays acceptably in almost every feed placement across Facebook, Instagram, LinkedIn, and Pinterest. That said, 1080 x 1350 (4:5) takes up more mobile screen and usually earns more attention, so use 4:5 when a placement supports it and fall back to 1:1 when you need one image everywhere.

Do social media ads have to be square?

No. Square (1:1) is the most versatile, but vertical formats like 4:5 and 9:16 take up more of a mobile screen and generally outperform square in feeds and full-screen placements. The best practice in 2026 is to produce the square, the 4:5 vertical, and the 9:16 vertical, then let each placement use the one that fits it natively.

What resolution should social media ads be?

1080 pixels on the short edge used to be the universal baseline, and it is still a safe floor everywhere. Meta has since moved above it: its current recommendations are 1440 x 1800 for 4:5 feed and 1440 x 2560 for 9:16 Stories and Reels. So design at 1440 on the short edge for Meta placements and keep 1080 as the baseline for platforms that have not raised their guidance. Going lower than 1080 makes images look soft in any feed.

Can I use the same image for every platform?

You can, but you should not. A single square jammed into a 9:16 slot looks cropped, and TikTok penalizes creative that reads as repurposed. The better approach is native crops per surface from one source, which modern ad makers produce automatically, so you get the right size for each platform without designing five separate files. For still image ads specifically, the static ad maker renders every ratio in this table from one input.
