Use 1080 x 1920 pixels for Instagram Reels. That is the sweet spot. It gives you a vertical 9:16 aspect ratio, fills the screen, and keeps your video crisp. If you remember only one thing, remember this size.
TLDR: Make Reels at 1080 x 1920 px, use a 9:16 ratio, and keep text away from the top and bottom. Put key words, faces, and logos in the center safe zone. For example, a small brand posting 20 Reels in one month might lose clicks if the “Shop Now” text sits under the caption area. Moving it up by about 300 pixels can make the video easier to tap and read.

Think of a Reel as a phone screen. Tall. Slim. Vertical. If your video fills that shape, you are doing it right.
What is the best size for Instagram Reels?
The best Instagram Reel dimension is 1080 pixels wide by 1920 pixels tall.
This is the standard vertical format for most phones. It fills the screen without black bars. It also gives Instagram enough detail to compress the video without turning it into mashed potatoes.
Can you upload bigger files, like 2160 x 3840? Yes. Should you? Usually, no. Instagram will compress your video anyway. A clean 1080 x 1920 export is often faster, lighter, and safer.
Can you upload 720 x 1280? Yes. It can work. But it may look soft, especially on newer phones. Use 1080 x 1920 when you can.
What aspect ratio should Instagram Reels use?
The ideal Instagram Reel aspect ratio is 9:16.
Aspect ratio is just the shape of the video. Not the exact size. A 1080 x 1920 video is 9:16. A 720 x 1280 video is also 9:16.
Instagram Reels support other ratios, but they can cause awkward crops. Honestly, it feels like Instagram enjoys hiding important text exactly where your buttons appear. So make the video vertical from the start.
Common aspect ratios
- 9:16: Best for Reels. Full screen.
- 4:5: Often shown in the main feed preview.
- 1:1: Used for some profile grid previews.
- 16:9 wide: Not ideal for Reels. It may show empty space or feel tiny.
Instagram Reel safe zones
This is where things get annoying.
Your Reel may be 1080 x 1920, but not every pixel is safe. Instagram places buttons, captions, profile names, likes, comments, and audio info over your video. If your text sits there, people may not read it.
Use this safe zone rule:
- Keep key text away from the top 250 pixels.
- Keep key text away from the bottom 350 pixels.
- Keep important details away from the right 150 pixels.
- Keep faces, product shots, and calls to action near the center.
The safest area is the middle chunk of the screen. Place your hook there. Place captions there. Place “Tap to save” there. Do not tuck your best line at the bottom. Instagram will sit on it like a cat on a laptop.

Your Reel cover should also be 1080 x 1920 pixels. This fits the full Reel view.
But there is a twist. Your cover may appear in different crops across Instagram. On the Reels tab, it can look tall. In your profile grid, it may appear as a square. In the feed, it may appear closer to 4:5.
So design your cover like this:
- Use a full 1080 x 1920 canvas.
- Put the headline in the center.
- Keep the main subject visible in a square crop.
- Avoid tiny text near the edges.
- Check the preview before posting.
Expect to waste time on this once or twice. The cover can look perfect in one place and weird in another. A centered layout saves you from most of that nonsense.
Instagram Reel upload specifications
Use these settings when exporting your Reel from an editor.
- File format: MP4 is best. MOV also works.
- Video codec: H.264
- Audio codec: AAC
- Resolution: 1080 x 1920 px
- Aspect ratio: 9:16
- Frame rate: 30 fps is safe. 60 fps can work too.
- Audio: Stereo, 44.1 kHz or 48 kHz
- File size: Keep it under 4 GB
For bitrate, a range of 8 to 12 Mbps is usually fine for 1080p video. If your Reel has fast motion, use the higher end. If it is mostly talking head footage, the lower end is fine.
How long can an Instagram Reel be?
Reel length can change as Instagram updates the app. In many accounts, Reels can be up to 90 seconds when made inside the app. Some uploaded videos may be treated as Reels at longer lengths.
Still, shorter often wins. A tight 12-second Reel can beat a slow 60-second one. Cut the dead air. Start with the best moment. People scroll fast. They do not owe your intro anything.
Best text size for Reels
Use big text. Bigger than you think.
A good minimum is around 60 to 80 pixels tall on a 1080 x 1920 canvas. For hooks, go larger. Around 90 to 120 pixels works well for many designs.
Use high contrast. White text on a dark box works. Black text on a pale background works. Thin yellow text over a busy kitchen clip does not work. We have all suffered enough.
Feed preview dimensions for Reels
Reels can show in the main feed. When they do, Instagram may crop them to 4:5. That means viewers may see a 1080 x 1350 style crop before tapping.
So keep your first frame clean. Put the hook near the center. Do not place key text at the very top or bottom. If the feed crop chops off your headline, fewer people may stop.
Profile grid crop for Reels
Your profile grid may show a square preview. That square comes from the center of your cover. This is why centered cover design matters.
Here is a quick cover test:
- Open your 1080 x 1920 cover.
- Imagine a square in the center.
- Ask: can I still read the main title?
- Ask: is the face or product still visible?
- If not, move things inward.
Quick checklist before uploading
- Canvas is 1080 x 1920 px.
- Video is vertical 9:16.
- Text is inside the safe zone.
- Cover works in tall and square crops.
- Audio is clear.
- File is MP4 with H.264.
- First 2 seconds have a strong hook.
- No tiny text near the bottom.
Common Reel dimension mistakes
Mistake one: uploading a wide video with empty space above and below. It looks small. It feels reused. People notice.
Mistake two: placing captions under Instagram’s buttons. This hurts watch time because viewers have to work harder.
Mistake three: designing covers only for the full vertical view. Then the profile grid crops the best part. Painful.
Mistake four: exporting at a strange size like 1000 x 1800. Instagram may still accept it, but compression can get ugly.
Simple final rule
Make every Reel 1080 x 1920 px. Keep it 9:16. Place the good stuff in the center. Use MP4. Check your cover crop. That is the whole game.
If your Reel looks clean, fills the screen, and keeps text away from Instagram’s buttons, you are already ahead of many posts in the feed.
