Crop Image Aspect Ratios for Instagram, TikTok, Pinterest

Every social platform has its own preferred image aspect ratio, and cropping wrong is the difference between a polished post and one with awkward white bars or cut-off faces. This is a quick reference for the aspect ratio each major platform actually uses in 2026, plus the free image crop aspect ratio tool that handles all of them in one place.


Quick Reference Table — Aspect Ratios by Platform

  • Instagram square post1:1 (1080×1080 px)
  • Instagram portrait post4:5 (1080×1350 px)
  • Instagram Story / Reel9:16 (1080×1920 px)
  • TikTok video / cover9:16 (1080×1920 px)
  • YouTube thumbnail16:9 (1280×720 px)
  • YouTube Shorts9:16 (1080×1920 px)
  • Pinterest standard pin2:3 (1000×1500 px)
  • Pinterest video pin9:16 or 1:1
  • Facebook feed image1.91:1 (1200×630 px)
  • Facebook link card1.91:1 (1200×630 px)
  • LinkedIn post image1.91:1 (1200×627 px)
  • Twitter / X post image16:9 (1200×675 px)

Save this list. The aspect ratio is the part that matters — the exact pixel dimensions just need to match the ratio at the highest resolution you have.


Why Cropping to the Right Aspect Ratio Matters

Each platform crops your image automatically if you don't match its expected aspect ratio. That auto-crop almost never lands where you want it. Faces get cut, logos disappear, important text gets centered on a corner.

Three things go wrong when you skip cropping:

  • Wrong subject framing — the platform crops to its own center, not yours
  • White or black bars — Instagram especially adds bars when the source ratio doesn't match
  • Compression artifacts — if the source is larger than the display size, platforms compress aggressively. Cropping first gives you control over what gets sacrificed

Pre-cropping to the exact ratio takes ten seconds and eliminates all three. It also tends to produce better engagement because the focal point lands where you put it, not where an algorithm guesses.


How to Crop an Image to a Platform's Aspect Ratio

Open the crop image aspect ratio tool, upload your photo, and use the preset row above the image. Each preset is labeled with both its ratio and the platform it serves:

  • 1:1 Square — Instagram post, profile picture, square avatars
  • 4:5 Portrait — Instagram portrait post (better engagement than 1:1 in feed)
  • 9:16 Story / Reel — Instagram Story, Instagram Reel, TikTok, YouTube Shorts, Snapchat
  • 16:9 Video — YouTube thumbnail, Twitter/X post, Facebook video cover
  • 2:3 Pin — Pinterest standard pin (the most-pinned ratio on the platform)
  • 1.91:1 FB / LinkedIn — Facebook feed, Facebook link card, LinkedIn post image, Open Graph
  • 4:3 Standard — classic 4:3 display ratio for general use
  • 3:2 Photo — DSLR photo standard ratio
  • Free — no aspect ratio lock, drag any rectangle

Pick a preset, drag on your image to choose what to keep, and download. The selection stays locked to the ratio regardless of how you drag. Output downloads in the same format as the input.


Pinterest Pin Aspect Ratio (2:3) — The One Most People Get Wrong

Pinterest is the platform where pre-cropping pays off most. The 2:3 vertical ratio (e.g., 1000×1500 px) is what Pinterest's algorithm shows in standard feed search results. Wider images get squeezed visually below taller ones — even when your image is technically higher quality.

If you're producing pins for product launches, blog promotion, or recipe-style content, crop to 2:3 before uploading. Pinterest itself recommends this in their creator docs.

The same applies to Instagram Story / Reels — anything that's not 9:16 either gets letterboxed or shows ugly background fill. TikTok is even stricter; the 9:16 frame is the entire viewing area.


When to Crop vs. When to Resize

These two operations are different and often confused:

  • Crop removes pixels outside the selection area. Use when the source image has the wrong shape (you only want part of it) or the wrong aspect ratio.
  • Resize scales the whole image up or down while keeping the same shape. Use when the aspect ratio is already correct but the dimensions are wrong (e.g., a 4000×6000 Pinterest pin that needs to be 1000×1500).

A typical social media workflow is: crop first to the right aspect ratio, then resize to the platform's recommended pixel dimensions. If you skip step one and only resize, you'll either distort the image or get an output that's the right size but wrong shape.


Privacy: Nothing Uploaded

The crop tool runs entirely in your browser using the Canvas API. Your image is never uploaded to any server — the cropping happens locally, the download is generated from your browser. This matters if you're cropping screenshots, family photos, draft product mockups, or anything you don't want third-party servers touching.

Works on JPG, PNG, WEBP, and GIF. The output keeps the input format.

The shortest path to better social media images is: crop to the right aspect ratio first, then worry about everything else. Once that one habit is in place, your posts stop looking awkward and your content stops getting cut.
