Social Media Image Sizes in 2026 (Plus a Free Browser Cropper)
Platforms still punish the wrong aspect ratio with awkward crops. Use this cheat sheet, then frame subjects with Kamero’s free social media image cropper—presets and pan controls, no upload. Whether you post wedding teasers, YouTube thumbnails, or LinkedIn event recaps, starting from the right canvas saves re-exports.
Common presets (pixels)
- Instagram square: 1080×1080
- Instagram portrait: 1080×1350
- Instagram / WhatsApp story: 1080×1920
- Facebook post / link share: ~1200×630
- YouTube thumbnail: 1280×720
- LinkedIn post: ~1200×627
Platforms tweak UI safe zones often. Treat these as practical starting points and leave padding around faces for stories. Always preview on a phone before you schedule a campaign.
Why crop locally
Uploading a full wedding master just to crop a teaser still exposes the original. Browser cropping keeps the master on your disk. Add a text watermark before posting proofs. If you also need a smaller file after the crop, run the compressor next—still without a server round-trip.
Framing tips by platform
Stories: keep faces away from the top sticker zone and bottom reply bar. YouTube thumbnails: leave room for bold text on one side; faces read better slightly off-center. LinkedIn: prefer clean horizontal frames that survive feed compression. Instagram portrait: maximizes phone real estate for couple portraits without the ultra-tall story crop.
Workflow for photographers
- Select the hero frame from your edit.
- Open the cropper and pick a preset.
- Pan so eyes sit in the safe zone.
- Export JPG for photos; PNG for sharp graphics; WebP when the destination allows.
- Watermark previews if the crop will leave your controlled gallery.
Repurposing one wedding frame
One ceremony aisle shot can become a square grid post, a story teaser, and a YouTube thumbnail for a highlight reel. Export three crops instead of shooting three compositions when time is short. Keep the uncropped master for print and client delivery via Kamero photo sharing.
Safe zones and text overlays
If you add captions in Instagram or YouTube Studio, leave empty space where UI chrome and subtitles live. A tightly framed face that looks perfect in the cropper can still get covered by a sticker later. For thumbnails, high contrast between subject and background beats tiny facial detail that disappears at small sizes.
Photographers posting daily can keep a folder of pre-cropped templates—square, portrait, story—exported once from selects. Refresh the folder after each shoot so social never waits on a full Lightroom export when inspiration hits.

FAQ
Do I still need Canva?
Canva shines for multi-layer designs. For a fast cover-crop from a photo, a dedicated cropper is faster and private.
Stories look cropped on mobile
Keep critical content away from the top and bottom UI. Pan slightly toward the center of the face.
Are these sizes official forever?
No. Social networks change templates. Recheck before a big campaign, and treat presets as living defaults.
Can I crop HEIC?
Export JPG from Photos first, then crop. Format conversion stays local with the converter when needed.
Carousels and multi-image posts
Carousel slides should share the same aspect ratio so the swipe feels intentional. Crop a set of selects to square or portrait once, then arrange the story arc: wide establishing frame, detail, emotion, detail, closing portrait. Mixed ratios in one carousel look accidental.
For paid ads, export the crop the ads manager requests—even if it differs from organic feed sizes. Mismatched ads get letterboxed or soft-cropped by the platform, wasting creative.
