Compare the real-world size of phones, tablets, laptops, consoles, watches — and everyday objects like a credit card or a banana 🍌 — side-by-side in 3D, at true relative scale.
→ size.fyi
- See any set of items next to each other in an interactive 3D view, or head-on in front / side / top.
- Everything is drawn to true relative scale, so a phone next to a tablet is exactly right.
- Switch between metric and imperial.
- Every comparison is a shareable link — e.g.
size.fyi/iphone-17-pro-vs-galaxy-z-fold8-open— and you can drop in custom dimensions too (my_box~200x300x100). - ~100 devices and objects in the catalog, and growing.
Missing something? There are two ways to get it in — pick whichever is easier for you:
- 📝 File an issue — no code required. Request an item with its name and dimensions (height × width × depth) and a link to the source, and we'll add it.
- 🔧 Open a pull request — add one small JSON file per item. See CONTRIBUTING.md for the format and a copy-paste template.
Accurate, manufacturer-sourced dimensions are the whole point, so a source link (spec page, product listing) is always appreciated.
