Why the right image size matters
Every social media platform has its own preferred formats — and anyone who just uploads an image "as is" leaves the platform in control of the crop. Three reasons why the exact target size pays off:
If your image doesn't fit the intended aspect ratio, the platform crops it automatically — usually centered, without regard for faces, logos or important details near the edges. The result: cropped heads, shifted compositions, lost visual impact.
If you deliver the wrong resolution, the platform scales it up or down — either way it costs sharpness. A too-small image looks mushy, a wrongly cropped one loses image content you actually wanted to show.
For businesses and brands, a consistent look across every channel matters. Delivering profile pictures, cover images and post graphics at the correct target size avoids distorted logos or shifted crops in your brand presence.
Knowing the target dimensions upfront means exporting correctly once instead of fixing it repeatedly. This saves noticeable time in the workflow, especially across several platforms at once.
Instagram formats in detail
Instagram offers several formats for different purposes. Since 2025/2026, the 4:5 portrait format (1080 × 1350 px) has been the recommended standard — it takes up more vertical space on the smartphone screen in the feed than the classic square, increasing your post's visibility while scrolling.
- Feed Square (1:1): 1080 × 1080 px — the classic, works everywhere.
- Feed Portrait (4:5): 1080 × 1350 px — more feed space, currently recommended.
- Feed Landscape (1.91:1): 1080 × 566 px — often heavily cropped in the feed, use with care.
- Story & Reels (9:16): 1080 × 1920 px — full-screen, vertical, identical for both Story and Reels.
- Profile picture: upload at 320 × 320 px, displayed at 180 × 180 px (cropped to a circle).
A white or colored border around your photo can be added directly for these formats — try our photo border tool: Instagram formats like 1:1 and 4:5 are available there as ready-made presets, and the rest of the canvas is automatically filled with your chosen border color, so nothing in your shot gets cropped.
Facebook, LinkedIn, TikTok, YouTube and Pinterest
Each platform has its own priorities: Facebook distinguishes between post image, cover image and profile picture, each with its own dimensions. LinkedIn clearly separates a personal profile from a company page. TikTok and YouTube Shorts share the vertical 9:16 format with Instagram Stories — one export often works for all three. YouTube thumbnails, in turn, follow the classic 16:9 video format, while Pinterest deliberately favors vertical scrolling with its tall 2:3 ratio.
You'll find the exact values for every platform and format in the calculator above, as well as in the full reference table further below.

Practical export tips
- Always export at the original resolution and only then scale down to the target size — never scale up.
- Keep important elements centered if you're unsure how heavily a platform will crop (e.g. Facebook link previews).
- Leave a safety margin on banners: Facebook cover images and YouTube channel banners get their edges cropped on mobile devices — important content belongs in the safe, centered area.
- For print, different rules apply than for screens — that's what our print size calculator is for, showing how large you can print a photo in cm.
For more images at once
Need to crop dozens of photos to Instagram format automatically?
This calculator shows you the right dimensions — BorderTool Pro by Michael Damböck then takes over the work: automatically cropping and framing entire photo series to Instagram formats like 1:1 or 4:5, including presets and batch export. Ideal if you don't want to adjust every image by hand.
Frequently asked questions about the social media image size calculator
What happens if my image has the wrong format?
The platform automatically crops your image to force it into the intended aspect ratio. This usually happens centered, without regard for important image elements — faces, logos or lines of text near the edges can get cut off. If you deliver the exact target size instead, you decide the crop yourself and quality stays fully intact.
Why do social media image sizes keep changing?
Platforms regularly adjust their layouts for new display sizes, app redesigns and user behavior — for example, Instagram increasingly pushed the 4:5 portrait format in 2025/2026 to use more feed space on smartphones. That's why an up-to-date calculator is worth more than a memorized number that could be outdated tomorrow.
Is a width of 1080 pixels enough for every platform?
For most feed and story formats on Instagram, Facebook and TikTok, yes — 1080 px width is the common baseline. But height and aspect ratio differ a lot: a 1080×1080 square doesn't map 1:1 onto a story (1080×1920) or a YouTube thumbnail (1280×720). Always check the exact height for the specific format, not just the width.
Which Instagram format is recommended in 2026?
The 4:5 portrait format (1080 × 1350 px) is currently the standard recommendation because it takes up more vertical space on screen in the feed than the classic 1:1 square. For stories and reels, 9:16 (1080 × 1920 px) remains the standard.
How do I export my photo at the right size?
In Lightroom, Capture One or Photoshop you can set a fixed pixel size when exporting. For quick cropping right in the browser, our free border tool offers common formats like 1:1 and 4:5 directly. For larger series and automated batch cropping to multiple formats at once, BorderTool Pro is the faster solution.
