Every Social Media Image Size That Matters in 2026

2026-05-18

Short answer: You don't need 40 sizes — you need about eight. Below is the clean reference list of the dimensions that actually matter in 2026, with safe-zone notes so nothing important gets cropped. When you've got one image and need it in five aspect ratios, ToolKoala's social media resizer crops to each platform's exact size in your browser, no upload, no account.

The sizes that actually matter (2026)

Keep this list. Almost everything else is a variation of these.

  • Instagram square post: 1080 × 1080 (1:1)
  • Instagram portrait post: 1080 × 1350 (4:5) — this gets the most feed real estate
  • Instagram Story / Reel: 1080 × 1920 (9:16)
  • X / Twitter in-stream image: 1600 × 900 (16:9)
  • Facebook feed image: 1200 × 630 (~1.91:1)
  • LinkedIn shared image: 1200 × 627 (~1.91:1)
  • YouTube thumbnail: 1280 × 720 (16:9)
  • TikTok video / cover: 1080 × 1920 (9:16)
  • Pinterest standard pin: 1000 × 1500 (2:3)

A few notes that save reuploads:

  1. Upload at 2x where you can (e.g. 2160 × 2160 for an IG square). Platforms downscale better than they upscale, and screens are sharp.
  2. Vertical wins on IG, TikTok, and Pinterest — portrait/9:16 fills more screen than square.
  3. YouTube thumbnails must be under 2 MB and 1280 × 720 minimum, or the upload is rejected.

Safe zones (the part everyone forgets)

The canvas size isn't the whole story — each platform overlays UI on top of your image.

  • Stories / Reels / TikTok (9:16): keep text and faces inside the middle ~80%. The top ~250px (username, time) and bottom ~400px (caption, buttons, the like/share rail) get covered.
  • Profile/cover images: these crop differently on mobile vs desktop. Center your subject.
  • Link preview cards (Facebook/LinkedIn 1200 × 630): text near the edges can get clipped by rounded corners in some clients. Pad your margins.

Rule of thumb: design for the canvas, but assume the outer 10–15% is decoration, not content.

The fast way to hit every size

The annoying part isn't knowing the numbers — it's exporting one design into all of them. That's the whole reason I built the resizer.

  1. Open ToolKoala's social media resizer.
  2. Drop your image in.
  3. Pick the target presets (IG square, Story, YouTube thumb, etc.).
  4. Adjust the crop focus so faces stay centered.
  5. Download each — or all at once.

It runs entirely in your browser, so the image never uploads. Check DevTools → Network if you want to confirm.

The honest alternatives

  • Canva (free tier): genuinely great if you also want to design, not just resize. The free tier covers most sizes; some "Magic Resize" niceties are behind Pro (~$120/yr). Your designs live on their servers.
  • Manual crop in Photoshop / GIMP / Preview: total control, but you're punching in dimensions one at a time, which is exactly the tedium the resizer removes.
  • Figma: overkill for resizing, but if you're already designing there, just set frame sizes from the list above.

If you're building a brand from scratch, Canva is the better all-in-one. If you already have the image and just need it cropped to spec, fast and private, that's what the resizer is for.

FAQ

What size should an Instagram post be in 2026? 1080 × 1080 for square or 1080 × 1350 for portrait. Portrait (4:5) takes up more vertical space in the feed, so it tends to perform better.

What is the correct YouTube thumbnail size? 1280 × 720 (16:9), minimum 640px wide, under 2 MB. YouTube rejects thumbnails that don't meet the minimum.

What's the best image size for a LinkedIn or Facebook link post? About 1200 × 627 (LinkedIn) and 1200 × 630 (Facebook), both roughly 1.91:1. Keep important text away from the edges so it isn't clipped in the preview card.

Do I have to make a separate image for every platform? No — start from one high-res image and crop to each ratio. ToolKoala's resizer does all the presets at once, locally in your browser.
