Meta Ads Creative Sizes in 2026: The Complete Guide

Meta Ads aspect ratios: 9:16, 4:5, 1:1 — Spilno Agency diagram
In 2026, Meta Ads creative sizes come down to three core aspect ratios: 1:1 and 4:5 for the Facebook and Instagram feed, 9:16 for Stories and Reels, and 1.91:1 for the right column and link ads. The universal resolutions are 1080×1080, 1080×1350 and 1080×1920 px. Below is the full table of Facebook ad dimensions by placement, plus image and video specs and the safe zones that keep your creative from being cropped.

Why creative size decides everything in 2026

Meta (Facebook + Instagram) shows a single ad across dozens of placements — feed, Stories, Reels, right column, Marketplace, Audience Network. Each one has its own screen geometry. Upload a creative in the wrong size and the system either crops it, pads it with empty bars, or simply skips it in some placements. The result is a lower CTR, a pricier click, and wasted ad budget.

In 2026 Meta has fully committed to the vertical video format (Reels, Stories) and to flexible creative (Advantage+ / Flexible), where you upload several aspect ratios and the algorithm picks the best fit for each placement. Knowing the current sizes is basic hygiene — without it, your ads simply underperform.

The three aspect ratios you must know

Instead of memorising dozens of pixel sizes, keep the aspect ratios in mind. Pixels are derived from them.

The three core aspect ratios in Meta Ads 2026
  1. 1:1 (square) — the all-rounder for the Facebook and Instagram feed and for carousel. Resolution 1080×1080 px.
  2. 4:5 (vertical portrait) — takes up more space in the mobile feed and drives a higher CTR. Resolution 1080×1350 px. The recommended format for static feed ads.
  3. 9:16 (full-screen vertical) — for Stories and Reels. Resolution 1080×1920 px.
  4. 1.91:1 (landscape) — Facebook right column and link ads. Resolution 1200×628 px.

If you are launching a campaign and do not want to cut ten variants, export three files: 9:16, 4:5 and 1:1. That is enough to cover 95% of all Meta placements.

The minimum image width Meta accepts is 600 px, but in practice you should not go below 1080 px on the short side — anything lower looks blurry on modern screens.

Image requirements

Video requirements

Video is the main performance driver in 2026, especially in Reels. The technical specs:

A typical video creative spec for Reels looks like this:

Format:        MP4 (H.264 + AAC)
Aspect ratio:  9:16
Resolution:    1080 x 1920 px
Frame rate:    30 fps
Length:        up to 90 s
File size:     up to 4 GB
Captions:      burned-in or .srt

Stories and Reels safe zones

This is the most common beginner mistake. A 9:16 frame is full-screen, but Meta overlays its own interface elements at the top and bottom: the avatar and account name up top, and the call-to-action (CTA) button and caption at the bottom. Put important text or a logo there and it gets covered.

Carousel

Advantage+ and flexible creative: the new 2026 standard

In Advantage+ Shopping and the Flexible format you upload several versions of one creative in different ratios, and the algorithm decides which to show in each placement. This widens reach and lowers CPM. The recommended kit for 2026:

  1. 9:16 (1080×1920) — for Reels and Stories;
  2. 4:5 (1080×1350) — for the feed;
  3. 1:1 (1080×1080) — for carousel, Marketplace and as a fallback.

Top 5 creative-size mistakes

  1. One square for every placement. In Reels a square shows with huge empty bars — low CTR.
  2. Text in the bottom zone of Stories. The button covers it and the user never sees the offer.
  3. Stretched video. A 16:9 upload in a vertical placement gives black bars or crops.
  4. Low resolution. A 600×600 creative looks blurry on modern displays.
  5. No captions. Up to 80% of views are sound-off; without captions the message is lost.

Quick pre-launch checklist

Frequently asked questions

What is the best creative size for Meta Ads in 2026?

The universal set is 9:16 (1080×1920) for Reels/Stories, 4:5 (1080×1350) for the feed and 1:1 (1080×1080) for carousel. These three files cover almost every placement.

Does the 20% text rule still apply?

No. Meta removed the hard limit in 2020. Ads with text are no longer rejected, but the algorithm still performs better with creatives that use less text.

What is the maximum file size for a Meta Ads video?

Up to 4 GB for video and up to 30 MB for images. The video format is MP4 or MOV with the H.264 codec.

What size should Reels ads be?

Aspect ratio 9:16, resolution 1080×1920 px, length up to 90 seconds. Keep key content in the centre of the frame, avoiding the top 14% and bottom 35%.
