Social media size guide: Instagram, TikTok and more

The standard Instagram post size is 1080×1350 px (4:5). Instagram accepts feed photos from 1.91:1 landscape to 3:4 portrait, so 1080×1440 is the tallest post you can make. TikTok, Reels, Stories and YouTube Shorts all use 1080×1920 px (9:16).

We checked every number on this page against the platform’s own help or ads pages, as of October 2026. Where a platform publishes nothing, we say so and name the source we used instead.

Instagram post size and dimensions

Instagram stores feed photos at up to 1080 px wide. A photo between 320 and 1080 px wide keeps its resolution if its ratio sits between 1.91:1 and 3:4. Wider files are scaled down to 1080 px, and anything outside that ratio range is cropped.

Format	Size (px)	Aspect ratio	Use it for
Portrait	1080 × 1350	4:5	Default for feed posts and carousels
Tall portrait	1080 × 1440	3:4	Most screen space; matches the grid
Square	1080 × 1080	1:1	Quotes, product shots
Landscape	1080 × 566	1.91:1	Wide photos (shows small)
Carousel	1080 × 1350	4:5	Up to 20 slides, one orientation
Stories	1080 × 1920	9:16	Full-screen Stories
Reels and Reels cover	1080 × 1920	9:16	Vertical video and its cover
Profile grid tile	1080 × 1440 (shown)	3:4	How every post looks on your profile

Instagram portrait size: 4:5 or 3:4?

Both work. 3:4 (1080×1440) fills more of the screen and matches the profile grid tile, so nothing gets trimmed on your profile. 4:5 (1080×1350) is the safer pick if you might run the post as an ad, because Meta’s Instagram feed ad spec still tops out at 4:5.

A 4:5 post loses about 34 px from each side in the 3:4 grid. Keep text a little away from the left and right edges.

Instagram aspect ratio for carousels

A carousel holds up to 20 photos or videos. The orientation you pick (square, portrait or landscape) applies to every slide, so export all slides at the same size. A 9:16 slide in a 4:5 carousel gets cropped to 4:5.

The Instagram carousel size guide covers panoramas that span several slides and other multi-slide layouts. For ready-made slide structures, see the Instagram carousel templates.

Stories, Reels and the profile grid

Stories and Reels are 1080×1920. Meta’s ads guide now recommends 1440×2560 for ads, which is the same 9:16 shape, so a 1080×1920 file works.

Since early 2025, the profile grid shows posts as 3:4 tiles cropped from the center. A Reels cover uploaded at 1080×1920 loses 240 px at the top and bottom on your grid, so put the cover title in the middle 1080×1440. Instagram’s help center doesn’t list the grid size; that figure comes from Hopper HQ’s September 2026 guide.

TikTok aspect ratio and video size

The TikTok aspect ratio is 9:16 and the standard TikTok video size is 1080×1920 px. TikTok’s ad specs ask for at least 540×960. They also accept 1:1 and 16:9, but those leave empty space on a phone screen.

Photo mode (slideshows) takes up to 35 photos per post. TikTok doesn’t publish a photo size; 1080×1920 fills the screen, and you can crop other ratios in the editor. The TikTok slideshow guide covers the rest of the workflow.

A TikTok profile photo must be at least 20×20 px. It displays as a circle, so upload a square of 200×200 or larger with the face or logo centered.

Safe zones for 9:16 posts

On TikTok, Reels, Stories and Shorts, the app draws your username, caption, buttons and progress bar over the image. The safe zone is the area those overlays leave alone. Here are the official numbers, converted to pixels on a 1080×1920 frame.

Platform	Top	Bottom	Left	Right	Based on
TikTok (video and photo mode)	240	660	120	120, plus button rail	TikTok in-feed safe zone template
Instagram Reels and Stories	269	672	65	65	Meta: 14% top, 35% bottom, 6% sides
Facebook Reels and Stories	269	672	65	65	Meta: same margins
YouTube Shorts	288	672	48	192	Google vertical video ad template

TikTok draws its template at 720×1280, so we scaled it by 1.5. The template also blocks a 180 px column for the like, comment and share buttons: x 780–960, from y 840 to the bottom.

One safe area for every app

If you post the same 1080×1920 file everywhere, keep text inside x 120–888 and y 288–1248. That 768×960 box clears every platform’s top and bottom overlays. Also leave the strip right of x 780 empty below y 840, where TikTok’s buttons sit.

All three sets of numbers come from ad templates, and ads carry an extra call-to-action button. Organic posts cover a little less, so these margins err on the safe side.

Facebook, YouTube Shorts, LinkedIn, Pinterest and X sizes

Platform	Format	Size (px)	Ratio
Facebook	Feed post	1440 × 1800 (1080 × 1350 also fine)	4:5
Facebook	Stories and Reels	1080 × 1920	9:16
YouTube	Shorts	1080 × 1920	9:16 (square allowed)
LinkedIn	Image post	1200 × 1200, 720 × 900 or 1200 × 628	1:1, 4:5 or 1.91:1
LinkedIn	Document (carousel) post	1080 × 1080 per page	1:1
Pinterest	Standard pin	1000 × 1500	2:3
Pinterest	Video pin	1000 × 1500	2:3 (1:1, 4:5, 9:16 also fine)
X	In-feed image	1080 × 1080, 1440 × 1800 or 1920 × 1080	1:1, 4:5 or 16:9

YouTube Shorts must be square or vertical, up to 3 minutes long and at most 1080p. LinkedIn document posts take a PDF, PowerPoint or Word file up to 100 MB and 300 pages. LinkedIn sets no page size for them, so pick one size and use it on every page.

What happens when you upload the wrong ratio

Each app handles a mismatch its own way:

• Instagram feed: a photo outside 1.91:1 to 3:4 is cropped to fit. A 9:16 slide becomes 3:4 and loses 240 px at the top and bottom.
• Instagram carousel: the orientation you pick applies to every slide, so mixed sizes get cropped.
• TikTok: a square or 4:5 photo shows smaller, with empty space around it, unless you crop it in the editor.
• YouTube: a horizontal video uploads as a regular video, not a Short.
• LinkedIn: vertical images taller than 4:5 get borders on the sides.
• Pinterest: pins taller than 2:3 may get cut off in the feed.

Text is what usually breaks. A crop that removes some sky is fine; a crop that slices a headline is not. Drop your image into the previewer above to check every crop before you post.

Export tips

1. Design at the final size. Start your canvas at 1080×1350 or 1080×1920 instead of resizing at the end.
2. Export 1080 px wide for Instagram. Instagram scales wider files down to 1080 px anyway.
3. Use PNG for text-heavy slides, JPG for photos. PNG keeps letter edges crisp; JPG keeps photo files small.
4. Keep one size per carousel. Export every slide from the same template.
5. Read it at phone size. Zoom out until the slide is about as big as it will be on a phone, then read every line.
6. Respect the safe zone on every slide. Captions and buttons cover every slide, not just the first one.

TokCloner rebuilds slideshows as 1080×1920 (9:16) PNGs, which fill TikTok, Reels and Stories. If you also post those slides in an Instagram feed carousel, keep the text in the middle 1080×1350, which survives both the 4:5 and the 3:4 crop. The TikTok slideshow maker page explains how it works.
