Convert an image to 9:16 ratio
A 9:16 ratio is tall and narrow — the exact shape of a phone screen held upright. It is the standard for full-screen vertical content: Stories, Reels, TikTok videos, and YouTube Shorts all expect 9:16, and a static image in this ratio will fill the entire screen with no black bars on either side.

How to convert your image to 9:16 ratio
Upload your image using the tool above.
For landscape photos, pad mode works best — it places the photo inside the tall frame and fills the sides with a neutral background rather than cropping most of the width away.
For already-tall photos, crop mode trims a small amount from the top and bottom.

Why do you need to convert to 9:16 ratio?
Stories, Reels, TikTok, and YouTube Shorts all use a 9:16 full-screen canvas. If your image is any other ratio, the platform adds black bars or crops it automatically — neither looks intentional. Converting to 9:16 before uploading means your image fills the entire screen exactly as you intended.
Common pixel sizes for this ratio (9:16)
Where this ratio is used
- Instagram and Facebook Stories
- TikTok videos and cover images
- Instagram Reels and YouTube Shorts thumbnails
- Phone lock-screen and home-screen wallpapers
Crop or pad — which should you use for this ratio?
Landscape photos rarely work well cropped straight to 9:16 — most of what made the shot wide simply disappears, and the subject can end up too zoomed in. Padding (adding blurred or solid bars to the sides) usually looks better for wide source photos being placed into a Story or Reel cover.
How this ratio compares to a similar one
9:16 vs 4:5: use 9:16 specifically when the destination is a full-screen vertical surface — Stories, Reels, TikTok, phone wallpapers. Use 4:5 when the destination is a normal feed post, where 9:16 content gets cropped down anyway.
Frequently asked questions
Is 9:16 the same as a phone wallpaper size?
It is the same ratio, but actual wallpaper resolution varies by phone model (e.g. an iPhone 15 is roughly 19.5:9, slightly taller than 9:16). Use 9:16 as a safe baseline; most phones crop it acceptably.
Why does my 9:16 image still show black bars on Stories?
Black bars appear when the uploaded image isn't exactly 9:16. Even a slightly different ratio (like 9:18) gets letterboxed by the platform. Converting precisely to 9:16 before uploading removes the bars.
Should I crop or pad a landscape photo to 9:16?
Cropping a wide landscape photo down to 9:16 removes most of the width, often losing the subject. Padding (adding blurred or solid color bars on the sides) is usually the better choice for landscape source images going onto Stories.
What's the safest area to keep text inside a 9:16 image?
Keep important text and faces within the middle 80% of the frame, away from the very top and bottom — many apps overlay their own UI (captions, icons, progress bars) in those edge zones.
Can I use 9:16 for a YouTube Short thumbnail?
Yes — YouTube Shorts uses the same 9:16 vertical frame as Stories and Reels, so an image converted to this ratio will display correctly without letterboxing.
