Facebook ad sizes in 2026 center on three ratios: Feed images at 4:5, which Meta now recommends at 1440 by 1800 pixels, full-screen Stories and Reels at 9:16, recommended at 1440 by 2560, and carousel cards at 1:1 square from 1080 by 1080 up. Those recommended resolutions moved up from the familiar 1080-series numbers, which are still accepted but are now below what the placements are built to display.
If you memorized 1080 x 1080 and 1080 x 1920, nothing you built is broken. Both clear Meta's minimums and will run without a warning. They are simply softer than the current recommendation on a modern phone, and on Feed specifically, square gives up vertical screen space to the 4:5 ratio Meta now points you at. The full cross-placement reference is on our Meta ad sizes and creative specs page.
Core Facebook and Meta ad sizes
| Placement | Recommended size (px) | Aspect ratio | Minimum |
|---|---|---|---|
| Feed image (recommended) | 1440 x 1800 | 4:5 | 600 x 750 |
| Feed image (square, still accepted) | 1080 x 1080 | 1:1 | 600 x 600 |
| Feed image (landscape) | 1200 x 628 | 1.91:1 | 600 x 314 |
| Stories | 1440 x 2560 | 9:16 | 500 px wide |
| Reels | 1440 x 2560 | 9:16 | 500 px wide |
| Right column (desktop) | 1200 x 628 | 1.91:1 | 600 x 314 |
| Carousel card | 1440 x 1440 | 1:1 | 1080 x 1080 |
| In-stream video | 1280 x 720 | 16:9 | 1280 x 720 |
Images are JPG or PNG up to 30 MB across every placement above. Aspect ratio tolerance is 3 percent on Facebook Feed and 1 percent on Instagram placements.
Why 4:5 is the workhorse for Feed
The 4:5 vertical format, now recommended at 1440 by 1800 and formerly built at 1080 by 1350, takes up more vertical space in the mobile Feed than a landscape or square image, which means more of the screen is yours as someone scrolls. That is why Meta lists it as the recommended Feed ratio rather than treating square as the default. Carousel placements are the one exception that stays square, and the Facebook carousel ad specs cover the per-card limits. Many advertisers default to 4:5 for Feed placements and 9:16 for Stories and Reels, then add a 1:1 square as a flexible fallback. If you only make one Feed asset, a 4:5 vertical is usually the strongest choice on mobile, where the majority of impressions happen.
Text and caption limits
Meta truncates long copy, so the first lines matter most. As a working guide:
- Primary text: around 125 characters before it gets cut with a "See more" link on most placements. Front-load the hook.
- Headline: keep it tight, roughly 27 to 40 characters reads cleanly without truncation across placements.
- Description: short, around 27 to 30 characters where it shows; it does not appear on every placement.
Generating copy that respects these limits by default saves a round of edits. An ad copy generator can draft primary text, headlines, and descriptions already shaped to fit Feed and Stories.
File and format specs
- Format: JPG or PNG for images; MP4 or MOV for video.
- Resolution: use the largest size available; Meta downscales cleanly but never upscales.
- Aspect ratio tolerance: stay within the recommended ratios so the platform does not auto-crop in ways you did not intend.
- Safe zone for Stories and Reels: keep text and logos out of the top 14 percent, the bottom 35 percent, and 6 percent of each side. The bottom figure is larger than most guides report, because the caption, sound attribution and call to action button stack there. We break the pixel math down in Meta ad safe zones.
The resizing problem, and how to skip it
The reason ad sizing eats so much time is that one campaign needs several of these at once: a 4:5 Feed, a 1:1 Square, and a 9:16 Story, minimum. Recomposing the same creative for each ratio by hand, so the product stays centered and nothing important gets cropped, is tedious work. An ad resizer that handles every placement in one pass does that recomposition for you, adjusting the layout per ratio rather than just stretching one image. Adscreator does this in the same run that writes your copy and generates your images, so you get every Facebook size at once with flat pricing and no per-export credits. If you are building the ads themselves rather than just resizing them, the Facebook ad maker starts from a product URL and returns all of these sizes together.
A quick checklist before you publish
- Feed asset at 4:5 (1440 x 1800 recommended, 1080 x 1350 still accepted).
- Stories and Reels at 9:16 (1440 x 2560) with safe zones respected.
- Primary text hook in the first 125 characters.
- Headline under 40 characters.
- Largest-resolution files exported in JPG, PNG, or MP4.
Once your dimensions are right, the faster move is to let one tool produce every Facebook size at once. See how the ad resizer turns a single creative into every placement without manual cropping.
