About SizeSide

SizeSide is a free tool that shows how tall things really are next to each other. You enter a few heights and it draws people, animals and everyday objects side by side on one shared scale.

Why we built it

Height charts are everywhere, but many of them are misleading. Some start the axis well above zero, which makes a small gap look huge. Others are slow, cluttered or hard to use on a phone. We wanted a clear, fast chart that tells the truth.

What we care about

• True scale. The chart always starts at zero, so a gap looks as big as it really is.
• Privacy. The tool runs in your browser. The heights you type are not sent to our servers.
• Plain and fast. No sign-up, no clutter, and it works on a phone.
• Many languages. SizeSide is available in English, Spanish, Japanese, French, German, Portuguese, Korean and Italian.
