Social Media Post Size Guide – all your social websites

Social Media Post Size Guide Introduction:

I’m constantly having to re-google “Social Media Post Size Guide” and no reliable single site ever pops up that I can trust. So i’m always searching for the correct size/quality/ratios for a variety of social media platforms and if I take a break from any I’m always forgetting my previous settings. So as a fail-safe I’m going to document them all here for myself and if you find it useful feel free to bookmark it. I’ll try to timestamp and update it as I find new platforms; I want this to be a working, living Social Media Post Size Guide so if you find an error, let me know. (Drop me a DM via Instagram.) The links to sources are there to help give you confidence that the information is up to date.

Workflow TIP:

Plan your content and exports to make it easier for you and ensure a correct naming convention to avoid duplicates. An example of this might be FILENAME-FB2048-ORIG-FILE-NAME.jpg as an export from Lightroom – at a glance you can identify the file size and the intended platform. This might also be suitable for Instagram, as well as avoiding duplicate output files.

INSTAGRAM – Social Media Post Size Guide

Rule of Thumb:  If you post higher quality photos than a website or service uses, it will resize your images. If you stick to the supported ratios, they will upload in the same quality as you created them. The resizing quality is dependant on your phone and the app, so to keep full control do the resizing yourself before uploading. If you are lucky and it looks OK letting the service resize it, that’s great news, just know that this doesn’t work for all phones/apps/services.

Tips: If you are having trouble uploading video try H265 – this has caused a lot of problems for some trying to upload H264 format.

YOUTUBE – Social Media Post Size Guide

Rule of Thumb: 

Youtube has video as its main format but it is slowly adding new features over time that are accessible to the biggest creators. As a rule of thumb you can upload in the highest quality but YouTube users can pick to watch at lower settings, just because you can upload at a higher resolution it’s not a requirement for the best quality.

Youtube Video

Size and Quality

 Encoding Settings:

Video Container: MP4
Audio Codec: AAC-LC
– Stereo or Stereo + 5.1
– Sample 96khz or 48khz

Video Codec: H.264
– Progressive Scan ( No Interlacing)
– High Profile
– 2 consecutive B Frames
– Closed GOP, GOP of half the frame rate
– CABAC
– Variable Bitrate (No limit reccomended below)
– Chroma Subsampling: 4:2:0

Frame Rate
Content should be encoded and uploaded in the same frame rate it was recorded.

Common frame rates include: 24, 25, 30, 48, 50, 60 frames per second (other frame rates are also acceptable).

Interlaced content should be deinterlaced before uploading. For example, 1080i60 content should be deinterlaced to 1080p30, going from 60 interlaced fields per second to 30 progressive frames per second.

Bitrate: (See the full source for more info)

TypeVideo Bitrate, Standard Frame Rate
(24, 25, 30)
Video Bitrate, High Frame Rate
(48, 50, 60)
2160p (4k)35-45 Mbps53-68 Mbps
1440p (2k)16 Mbps24 Mbps
1080p8 Mbps12 Mbps
720p5 Mbps7.5 Mbps
480p2.5 Mbps4 Mbps
360p1 Mbps1.5 Mbps

Ratios:

The standard aspect ratio for YouTube on desktop is 16:9. If your video has a different aspect ratio, the player will automatically change to the ideal size to match your video and the viewer’s device.

For some combinations of video and device aspects ratios, such as 9:16 vertical videos on desktop browsers, YouTube may add additional padding for optimal viewing. The padding is white by default, and dark gray when Dark theme is turned on.

For best results, avoid adding padding or black bars directly to your video. This interferes with YouTube’s ability to adjust the player dynamically to your video size and the viewer’s device.

For the default 16:9 aspect ratio, encode at these resolutions:

  • 2160p: 3840×2160
  • 1440p: 2560×1440
  • 1080p: 1920×1080
  • 720p: 1280×720
  • 480p: 854×480
  • 360p: 640×360
  • 240p: 426×240
