Facebook Ad Image Sizes: Aspect Ratios and Safe Zones
Meta publishes six official ad aspect ratios — 1.91:1, 16:9, 1:1, 4:5, 2:3 and 9:16 — and allows up to 10 images or videos per ad. The old "20% text rule" does not appear in Meta's current guidance at all; today's rule is safe zones.

Key facts
- Meta's official ad aspect ratios are 1.91:1, 16:9, 1:1, 4:5, 2:3 and 9:16, with up to 10 images or videos per ad.
- Catalog product images must be JPEG or PNG and no larger than 8 MB; Meta recommends at least 1 image per product and 4 or more.
- Shops product images are square 1:1 at a minimum of 500 x 500 px, with 1024 x 1024 px recommended.
- There is no current 20% text rule — the old percentage rule is absent from Meta's official guidance, which now specifies safe zones instead.
- For 9:16 creative keep the top, bottom and side edges clear of key elements, text and logos; for Instagram Feed at 1:1 or 4:5 keep the bottom and sides clear; Reels disclaimers must leave the bottom 40% clear.
- Single-image ad minimum dimensions and maximum file size: Meta publishes 0 figures for both, so both limits remain unverified.
Square (1:1) creative
Square format is a reliable, broadly compatible choice across feed placements on both desktop and mobile, since it displays at a consistent size without significant cropping in most feed contexts. It's a reasonable default when running one creative across multiple placements without building separate versions for each.
Vertical 4:5 creative
A 4:5 vertical ratio takes up more vertical space in a mobile feed than a square image, which generally means more screen real estate and attention as someone scrolls past. This ratio works well for feed placements specifically but isn't as tall as the format Stories and Reels expect.
Full vertical 9:16 for Stories and Reels
Stories and Reels placements expect a full-screen vertical 9:16 ratio. Using a square or 4:5 image here typically results in visible bars or a cropped, zoomed-in version of the image that loses composition control — building creative natively in 9:16 for these placements avoids that problem entirely.
Safe zones and UI overlap
Regardless of ratio, leave margin around the edges of the frame — profile names, captions, call-to-action buttons, and interactive elements like the Stories reply bar or Reels like/comment icons typically sit near the top and bottom or right edge of vertical placements. Keep essential text and product detail centered and away from those regions so nothing important gets covered.
| Placement | Aspect ratio | Size and file rules | Text and safe-zone rules |
|---|---|---|---|
| Facebook Feed | 1.91:1, 16:9, 1:1, 4:5, 2:3 | Single-image ad minimum dimensions and max file size are not published — not verified | No text or watermark overlaying the product, no calls to action, promo codes or time-sensitive price text |
| Instagram Feed | 1:1, 4:5 | Square 4:5 and 1:1 creative, up to 10 images or videos in the ad | Keep the bottom and sides clear of key elements, text and logos |
| Facebook and Instagram Stories | 9:16 | Full-screen vertical, up to 10 images or videos in the ad | Keep the top, bottom and side edges clear of key elements, text and logos |
| Instagram Reels | 9:16 | Full-screen vertical creative | Disclaimers must leave the bottom 40% of the frame clear |
| Reels disclaimer placement | 9:16 | Bottom 40% of the frame reserved for the disclaimer | Nothing else in the bottom 40%: no text, logos or key product detail |
| Shops product images | 1:1 square | At least 500 x 500 px, 1024 x 1024 px recommended, JPEG or PNG | Use product images on a white backdrop; do not overlay text or watermarks |
| Catalog product images | Not specified by Meta | JPEG or PNG, 8 MB maximum per image; 1 image minimum, 4 or more recommended | No text over the product, no watermarks, no promo codes |
| Single-image ads | 1.91:1, 16:9, 1:1, 4:5, 2:3, 9:16 | Minimum dimensions and max file size: not published | Safe zones replace the retired percentage-based text rule |

Frequently Asked Questions
Can text be over my Facebook ad image?
Yes, but not over the product itself, and it has to respect the placement's safe zone: in 9:16 keep the top, bottom and side edges clear, and for Reels disclaimers leave the bottom 40% of the frame clear.
What aspect ratio should a Facebook ad image be?
Meta officially supports 1.91:1, 16:9, 1:1, 4:5, 2:3 and 9:16 — use 9:16 for Stories and Reels, 4:5 for a tall feed image, and 1:1 as the safest single version across feed placements.
Is the 20% text rule still in force on Facebook ads?
No. The 20% text rule is not in Meta's current official guidance at all — there is no percentage-based text limit published today, and the replacement guidance is safe zones at 9:16, 1:1 and 4:5.
How many images can I put in a Facebook catalog ad, and how big can each file be?
Catalog product images must be JPEG or PNG at 8 MB maximum, with at least 1 image per product and 4 or more recommended, while a single ad can carry up to 10 images or videos.
What size should a Facebook Shops product image be?
Square 1:1 at a minimum of 500 x 500 px, with 1024 x 1024 px recommended, on a white backdrop and with no overlaid text or watermarks.
What are the minimum dimensions for a single-image Facebook ad?
Meta does not publish a minimum dimension or a maximum file size for single-image ads, so Meta's own guidance leaves that figure unverified — treat any number you see for it as unconfirmed at the source, alongside the official 9:16 and 1.91:1 ratios.
Why Fluxx.work
Fluxx.work exports the same product image across multiple ad-ready aspect ratios, so each Facebook placement gets a properly composed version instead of a stretched or cropped square.
