What size is a Facebook ad?

1080 x 1350 pixels (4:5 portrait) is the best size for the Facebook feed, or 1440 x 1800 for the sharpest result. 1:1 square (1080 x 1080) also works in the feed, and Stories and Reels use 9:16 (1080 x 1920).

What size are Instagram ads?

1080 x 1350 pixels (4:5) for the Instagram feed, 1080 x 1080 for square, and 1080 x 1920 (9:16) for Instagram Stories and Reels.

What ratio should Meta ads be?

4:5 portrait for the feed is the default. 1:1 square and 9:16 vertical cover the other placements.

What are the safe zones for Instagram Stories and Reels ads?

Keep about 14% at the top, 35% at the bottom and 6% on each side free of text and logos. On a 1080 x 1920 frame that is about 269 pixels at the top and 672 at the bottom.

How long can a Meta ad headline be?

Meta recommends headlines of up to 40 characters, and about 125 characters of primary text before the rest is cut off behind See more.

What is the minimum image size for Meta ads?

600 pixels wide for Facebook Feed and 500 pixels wide for Instagram Feed. Design at 1080 pixels or more on the short edge so the ad stays sharp.

Does Meta still have a 20 percent text rule?

No. Meta removed the hard 20 percent text limit, but ads with less on-image text still tend to read more clearly on a phone.

Meta ad specs 2026: Facebook and Instagram ad sizes

Updated 15 October 2026

The best size for a Meta ad image is 4:5 portrait at 1080 x 1350 pixels, or 1440 x 1800 for the sharpest result, which is what Meta recommends. It fits the Facebook and Instagram feeds and fills the most screen on a phone. Stories and Reels use 9:16 at 1080 x 1920, with the top 14%, the bottom 35% and 6% on each side kept free of text. Images can be JPG or PNG up to 30 MB.

Meta crops or letterboxes anything that does not match a placement, so designing to these sizes keeps your ad looking intentional. The table covers every placement, followed by the Instagram and Facebook sizes on their own, the text limits and the safe zones. The specs were checked against Meta's ads guide and Business Help Centre in September 2026.

Instagram ad sizes

Instagram takes feed images anywhere from 4:5 portrait to 1.91:1 landscape, and 9:16 for Stories and Reels:

Instagram feed, portrait: 1080 x 1350 (4:5), or 1440 x 1800. The best choice for the feed.
Instagram feed, square: 1080 x 1080 (1:1).
Instagram feed, landscape: 1.91:1 is accepted, but it is the smallest on screen.
Instagram Stories and Reels: 1080 x 1920 (9:16), inside the safe zone below.
Minimum width 500 pixels. JPG or PNG, up to 30 MB.

Facebook ad sizes

Facebook Feed takes four ratios, and Facebook Stories and Reels use the same 9:16 frame as Instagram:

Facebook feed, portrait: 1080 x 1350 (4:5), or 1440 x 1800. The best default.
Facebook feed, square: 1080 x 1080 (1:1).
Facebook feed, landscape: 1200 x 628 (1.91:1), or 16:9.
Facebook Stories and Reels: 1080 x 1920 (9:16).
Minimum width 600 pixels. JPG or PNG, up to 30 MB.

Safe zones for Stories and Reels

In Stories and Reels the app covers the top and bottom of your ad with the profile name, caption and buttons. Meta advises keeping these areas free of text and logos. Some older Meta pages still show 20% at the bottom for Stories, but 35% is the current guidance and keeps you safe in both. Check your own image with the free safe zone checker.

Top: 14%, about 269 pixels on a 1080 x 1920 frame.
Bottom: 35%, about 672 pixels.
Sides: 6% each, about 65 pixels.
Reels ads with a disclaimer: keep the bottom 40% clear, about 768 pixels.

Text limits for Meta ads

Meta recommends about 125 characters of primary text, because longer text is cut off behind See more, and headlines of up to 40 characters. Put the hook in the first line, since many people never tap See more. The Facebook ad copy guide covers the words themselves.

Meta removed the old 20% rule on how much of an image can be text. Less text is still easier to read on a phone.

Video ad sizes

If you do run video, the same ratios apply. Use 4:5 or 1:1 for the feed and 9:16 for Stories and Reels, at 1080 pixels on the short edge. Keep the first second strong, and caption it, because most people watch on mute.

Which size should you actually use

If you make one asset, make it 4:5 for the feed, where most impressions happen. Add a 9:16 version for Stories and Reels when you can. A 1:1 square is a fine compromise if you need a single image to run everywhere. The free ad size checker tells you which placements an image fits.

The size is not the ad

A perfectly sized ad with a weak idea still fails. Pair the right dimensions with a proven structure: see how to make Meta ads and winning Meta ads. Mockingbird outputs finished static ads at 4:5 portrait, 1080 x 1350, ready to upload.
