Why dimensions matter
Each platform has its own rendering rules. Upload an image that is too tall and Twitter crops the sides in the feed preview. Upload one that is too wide for LinkedIn and the platform adds black pillarboxes. Get Product Hunt dimensions wrong and your hero UI is cropped out of the gallery thumbnail. These are avoidable problems — the right dimensions for each platform are fixed, and creating correctly-sized exports is a one-time setup cost that pays off every time you share.
X (Twitter) screenshot sizes
X displays up to four images per post. The key dimensions:
- Single image: 1200x675 px (16:9) fills the in-feed card without cropping. This is the safest dimension for a product screenshot.
- Two images: Each image shows at approximately 600x675 px side by side. Use square crops (1:1) or portrait crops (2:3) to fill the space cleanly.
- Four images: A 2x2 grid, each cell at 600x338 px. Only use four-image posts when each screenshot works as a standalone image at small size.
Maximum file size: 5MB for PNG. Export at 2x resolution (so 2400x1350 px for a 16:9 image) and let X downsample — the result is crisper than uploading at 1x.
LinkedIn screenshot sizes
LinkedIn has two distinct use cases for screenshots:
- Link preview (when you paste a URL): LinkedIn fetches the Open Graph image from your page. That OG image should be 1200x627 px. This is the image that appears when someone shares your landing page on LinkedIn — it is worth ensuring your site's OG image is a polished screenshot, not an autogenerated placeholder.
- Direct image post (when you upload images manually): 1200x1200 px (square) displays without cropping in the feed. Landscape images at 1920x1080 (16:9) work for horizontal UIs. Portrait at 1080x1350 (4:5) takes up the most vertical feed real estate and gets more stop-scroll attention.
For product launch announcements and feature reveals, a 4:5 portrait image with a device frame and gradient background tends to outperform plain landscape screenshots because it dominates more of the feed.
Product Hunt gallery sizes
Product Hunt screenshot galleries display at 1270x952 px (4:3 aspect ratio). Key things to know:
- The first gallery image becomes your feed thumbnail — center your most recognizable UI element.
- Product Hunt recommends 3–5 gallery images. The first should show the core value prop. Subsequent images can go deeper: specific features, the mobile experience, pricing, social proof.
- Animated GIFs are supported and often perform better than static screenshots for demonstrating interactions or transitions.
Upload PNG at 2x the display resolution (2540x1904 px) for maximum crispness on Retina displays.
App Store and Google Play (bonus)
- iPhone 6.9" (required for App Store): 1320x2868 px (portrait) or 2868x1320 px (landscape).
- Google Play feature graphic: 1024x500 px exactly — this is the banner shown at the top of your Play Store listing.
- Google Play phone screenshots: Minimum 320px on the short side, maximum 3840px on the long side, JPEG or 24-bit PNG.
One workflow for all platforms
Rather than re-styling your screenshot for each platform, create a master export at 2560x1440 px (16:9, 2x). From that master:
- Crop to 1200x675 for X posts.
- Crop to 1200x1200 (center crop) for LinkedIn square posts.
- Crop to 1270x952 for Product Hunt.
- Keep the master for OG images (it is already close to the 1200x627 OG spec — just trim the top and bottom).
In Shotcraft, set your canvas to the master resolution, style your screenshot once, and export. Then use any image editor to crop the derivatives — or use Shotcraft's preset export sizes for the platforms you need.
