Handy tools, free in your browser

Free, handy online tools — starting with size, screen and weight comparisons drawn to scale. No sign-up, nothing to install, and every picture can be downloaded or shared.

• 📏Size ComparisonPeople, animals, vehicles, buildings and planets side by side, to scale.
• 🖥️Screen Size ComparisonPhones, tablets, laptops, monitors and TVs: real width, height and area.
• ⚖️Weight ComparisonHow heavy is X compared to Y — and how many Y make one X.

Why we build these

Numbers on a spec sheet are hard to picture. A 65-inch TV has about twice the screen of a 46-inch one; a blue whale weighs as much as 25 elephants; a Boeing 737 is seven people tall. Our tools turn those numbers into pictures you can see, check and share — and new tools are added every couple of weeks.
