Furseka Size Lab

See how big it really is.

Enter an object's width, height and depth to compare it with familiar objects at the same scale. Use it when shopping or when explaining a product's size.

Compare my objects Images & embeds for stores

See it next to something you know

Try a plush toy example measuring 20cm wide, 30cm high and 27cm deep next to an iPhone 16 and A4 paper. Compare a figure by height alone, or enter your desk's width, height and depth.

Use the same comparison in a product listing

Turn product dimensions into a size comparison image, shareable link or responsive embed. Use the same comparison tool without signing up. Use this on a store that allows HTML iframes. Some platforms restrict embeds; use an image or share link in that case.

Compare outer dimensions at the same scale. This is not actual 1:1 screen size, and model details are illustrative.

Saved in this browser only when you allow it. There is no account or cloud storage. Inputs are included in the address and visible to anyone with the link.

Try it this way

Enter dimensions from a product listing or your own measurements. Width runs left to right, height bottom to top, and depth front to back.
Add a familiar reference such as a phone or A4 paper. For a person or figure with only a known height, use height-only mode.
Change the view and check the dimensions. Save an image or link, or take the same comparison to the store tools.
