Social media video sizes

How to use the social media video sizes

1. 01Choose a platform, or leave it on All to see every placement.
2. 02Read the dimensions and aspect ratio for that placement, and check the notes for whether the figure is a maximum, a minimum or the platform's own stated resolution.
3. 03Follow the source link to confirm file size, duration and any other limits on the platform's own page.

Instagram video sizes

Instagram Reels ads use a 9:16 vertical ratio, and Meta's ads guide states 1440x2560 pixels as the resolution for this placement, with a 4 GB maximum file size.

Instagram Feed video ads are also specified at 9:16, at 1080x1920 pixels, with the same 4 GB maximum file size and a 1% tolerance on the aspect ratio. Both placements are full vertical video: neither of the two Instagram ad pages linked here lists a separate square or 4:5 resolution.

Facebook Reels size

Facebook Reels ads match Instagram Reels ads exactly: 9:16 vertical at 1440x2560 pixels, a 4 GB maximum file size, and no stated maximum video duration on Meta's ads guide for this placement.

YouTube video sizes

A standard YouTube upload uses YouTube's default aspect ratio, 16:9, and YouTube Help's own recommended-resolution table lists 1920x1080 as its 1080p (HD) figure for that ratio.

The YouTube Shorts row here is sourced differently: it comes from Google Ads' Performance Max guidance, which recommends a 1080x1920, 9:16 vertical video asset, and states that a vertical video between 10 and 60 seconds long is what makes it eligible to run as a Shorts ad. YouTube Help's own page on Shorts eligibility confirms organic Shorts can run up to three minutes and must be square or vertical, but does not state pixel dimensions, which is why this row cites the Google Ads source instead.

TikTok video size

TikTok's Ads Manager documentation for auction in-feed ads states a minimum resolution of 540x960 pixels at a recommended 9:16 vertical ratio, with a maximum file size of 500 MB and a video length of up to 10 minutes.

That figure is a floor, not a fixed export size: TikTok's own wording is "more than or equal to" 540x960, so a higher-resolution vertical export at the same 9:16 ratio is accepted too.

LinkedIn video sizes

LinkedIn Marketing Solutions gives four video ad ratios for feed placements, each as a minimum and a maximum: landscape 16:9 from 640x360 up to 1920x1080, square 1:1 from 360x360 up to 1920x1920, vertical 9:16 from 360x640 up to 1080x1920, and vertical 4:5 from 360x450 up to 1080x1350.

This table records each ratio's maximum, with the minimum noted alongside it. Two of the four, the 9:16 and 4:5 verticals, share a top edge of 1080 pixels wide; the square option is the only 1:1 ratio in this table, and the landscape option is one of two 16:9 rows here, the other being YouTube's standard upload.

Questions about the social media video sizes

What size should a vertical video be?

There is no single fixed pixel size: most vertical placements on this page use a 9:16 ratio, but the stated figure varies by platform, from TikTok's minimum of 540x960 up to Meta's 1440x2560 for Instagram and Facebook Reels ads. LinkedIn also offers a less extreme 4:5 vertical option. Check the row, and its notes, for the platform you are exporting for rather than assuming one number covers all of them.

Can I post the same video to every platform?

Not without resizing. The placements on this page span four different ratios, 16:9, 1:1, 4:5 and 9:16, and a video shot for one will be letterboxed or cropped on a platform expecting another. Use the aspect ratio calculator to work out what a crop needs to fit each target ratio.

How often do these sizes change?

Platforms revise their specifications without much notice, which is why every row here links straight to the platform's own current page rather than treating a number as permanent. The date next to "Last checked" is when we last confirmed it against that page.

Where do these numbers come from?

Each row is checked directly against the platform's own official help or ads-specification page, Meta, TikTok, Google or LinkedIn, not a third-party roundup. The Source link on each row goes to the exact page we checked.
