How do I post a full video on Instagram without it being cropped?
Frame it in Instagram’s shape before you post: Shape 4:5 for the feed or 9:16 for Reels. The whole picture fits inside the border, so Instagram has nothing left to crop.

Add a border to a video for Instagram
Fit the whole clip in Instagram’s 4:5 post shape or a full-screen 9:16 Reel, framed in white, colour or blur, so nothing important gets cut.
To post a video on Instagram without cropping, give it a border in the shape Instagram wants. Open your clip above (this page starts on 4:5 with Clean white), choose a look, then press Export video. The whole frame sits inside the border, so the app has nothing to trim.
Instagram shows feed videos at up to 4:5 tall and Reels and Stories at 9:16. A landscape clip posted as it is either appears small in the feed or gets cropped when you zoom it to fill. Framing it at 4:5 makes it take up as much of the feed as Instagram allows, with a clean white edge many creators use as a signature look.
How to make an Instagram-ready framed video
Open the clip
Drop it on the tool. On this page Shape is already 4:5, the tall feed-post shape.
Pick where it’s going
Keep 4:5 for a feed post, or choose 9:16 under Shape for a Reel or a Story.
(enlarge image) 4:5 for a feed post; 9:16 for Reels and Stories.
- 4:5
- 9:16
Choose the look
Clean white is the classic Instagram border. Blurred background fills the space with the clip itself; Gradient adds colour.
Export and share
Press Export video. On a phone, tap Share and choose Instagram, or save it to Photos and post from the app.
Which shape for which part of Instagram
- Feed post: 4:5 (1080×1350 from a 1080p clip) takes up the most room. Square 1:1 also works and suits carousel posts that mix photos.
- Reels: 9:16 (1080×1920). Keep captions and faces away from the bottom fifth, where Instagram places its own buttons and text.
- Stories: 9:16 as well. A white or blurred frame keeps a landscape clip readable on a tall screen.
Your profile grid shows a cropped thumbnail of each post, so keep the subject roughly central. Moving the video inside the frame (drag the preview, or Top to bottom under More options) helps when a caption or logo needs space.
Getting the white Instagram border right
Accounts that use a white border on every post usually keep three things the same: the colour, the width and the shape. Use the same Border width each time (5% is a good start) and the same shape, and your grid will look deliberate. If pure white is too stark against Instagram’s dark mode, try the off-white swatch, or the Shadow card look, which puts the video on a white card over pale grey.
For a lower-third caption, the Polaroid look adds a deep bottom edge with optional text in four fonts.
Keep the quality up on upload
Instagram re-compresses everything you post. Give it a clean source: set Quality to High under Export settings and keep the size at 1080 on the short side, which is what Instagram displays. A 4K export only adds upload time, because Instagram scales it down anyway.
Instagram border questions
What size is a 4:5 Instagram video?
1080×1350 pixels when your clip is 1080p. A 720p clip gives 720×900; you can set the size under Export settings.
Why do people add white borders to Instagram videos?
To keep the whole frame visible, to make a landscape clip fill more of a tall feed, and for a consistent, gallery-like look across a profile.
Can I use a blurred background instead of white?
Yes. Choose Blurred background. The space around the clip is filled with a soft, moving copy of it, which looks full rather than framed.
Does Instagram remove the border?
No. The border is part of the video’s picture, so Instagram shows it as it is.
Can I add a border to an Instagram video on iPhone?
Yes, in Safari: open this page, choose the clip, export, then tap Share and choose Instagram or Save Video.
