Social Media Ad Sizes for 2026: The Complete Cheat Sheet

Three sizes cover the vast majority of social media ad placements in 2026: 1080 x 1080 pixels (1:1 square) for feed posts, 1080 x 1350 pixels (4:5 vertical) for Meta and LinkedIn mobile feeds, and 1080 x 1920 pixels (9:16 full vertical) for Stories, Reels, TikTok, and Shorts. 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.

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. Use 1080 x 1080 (1:1) or 1080 x 1350 (4:5) for feed ads, and 1080 x 1920 (9:16) for Stories and Reels. The 4:5 vertical takes up more screen on mobile and generally earns more attention than a square, so it is the better default for feed. Single-image link ads that show a headline and description below the image use 1200 x 628 (1.91:1).

On Stories and Reels, keep your logo, text, and any call to action inside the middle of the frame. The top and bottom roughly 250 pixels are where the profile name, caption, and buttons sit, and anything you place there gets covered. Upload as JPG or PNG at up to about 8 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.

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.

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?

Design at 1080 pixels on the short edge as a baseline. That gives 1080 x 1080 for square, 1080 x 1350 for 4:5, and 1080 x 1920 for 9:16, all of which are crisp on high-density phone screens. Going higher rarely helps because platforms compress on upload, and going lower makes images look soft in the 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.
