Meta Ads Creative Sizes in 2026: The Complete Guide

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.

Creative sizes and aspect ratios that cover 95% of Meta placements

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

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.

Full table of Meta ad creative sizes by placement

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

• File type: JPG or PNG. Use PNG for graphics with text and sharp edges, JPG for photos.
• Max file size: 30 MB.
• Recommended resolution: at least 1080 px on the short side.
• Text on image: Meta officially retired the old “20% text rule” back in 2020 — ads with text are no longer rejected. But the algorithm still favours creatives where text covers less of the frame, so don’t overload the image with copy.
• Colour profile: sRGB, so colours don’t shift after compression.

Video requirements

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

• Format: MP4 or MOV (recommended codec — H.264).
• Max file size: 4 GB.
• Frame rate: up to 60 fps.
• Length: feed — up to 241 min (15–60 s works best); Stories — up to 60 s per card; Reels — up to 90 s.
• Audio: stereo, AAC, bitrate from 128 kbps.
• Captions: essential — most people watch without sound. Add burned-in captions or an .srt file.

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.

• Top 14% (≈ 250 px) — keep clear: profile and name live here.
• Bottom 20% (≈ 340 px) in Stories and up to 35% in Reels — the CTA, caption and icon zone. Don’t place key text here.
• Centre ~66% — the safe zone. Keep all important content (offer, product, text) here.

Carousel

• Number of cards: 2 to 10.
• Aspect ratio: 1:1 for every card (resolution 1080×1080).
• Important: all cards must share the same ratio — the system won’t mix squares and verticals in one carousel.
• File: images up to 30 MB, video up to 4 GB per card.

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

• ✅ 9:16, 4:5 and 1:1 prepared
• ✅ Resolution ≥ 1080 px on the short side
• ✅ Key content within the centre 66% of the frame
• ✅ Video — MP4/H.264, up to 4 GB, with captions
• ✅ Image — JPG/PNG, up to 30 MB, sRGB
• ✅ Preview checked in every placement before publishing

Why it pays to produce the maximum number of creatives

The more distinct creatives you feed the Meta Ads system, the larger the share of the audience your campaign can reach. Each creative hooks its own segment — different pain points, visual styles and messages resonate with different people. Broader reach of a relevant audience feeds straight into the auction: the system finds more cheap, high-quality impressions and the average cost per click drops.

The second reason is the trigger itself. It’s the creative that decides whether a user stops and reacts to the offer, so its idea and execution directly determine campaign performance. One or two layouts give the algorithm no room to optimize — there’s nothing to pick a winner from. With many creatives, the system quickly discards the weak ones and scales those with the lowest cost per action. So the rule is simple: prepare as many variants as you can in every required size — and refresh them regularly to avoid creative fatigue.

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%.
