Print Size Calculator

How big an image prints, and how big it prints well.

It runs entirely in this browser tab: what you type is never uploaded, and every conversion says which published table or definition it came from.

How to use it

  2. Adjust the settings beside it until the result is what you wanted.
  3. Copy the result, or save it as a file. The result updates as you type.

Questions

Is what I type uploaded anywhere?
No. The whole application is carried as WebAssembly and runs on your own device. There is no server to send anything to, and none of these tools makes a network request while it works.
Why does a size converter keep telling me to check the maker's chart?
Because a size is a convention rather than a measurement. Two makers put different numbers on the same garment, and the same number on two shelves in one shop can differ by a whole size. What is converted here is a number; what decides whether something fits is the measurement it came from, which is why every one of these gives that too.
Which cup, which gallon, which gigabyte?
Whichever you choose — and the answer says so. There are four cups in common use, two gallons, two pints and two meanings of a gigabyte. A converter that picks one silently is wrong for everybody who meant the other.
Why will the wire tool not give a current rating?
Because that number is not a property of the metal. What a conductor may safely carry depends on its insulation, how it is installed, whether it is bundled with others, the ambient temperature and the wiring regulations where you are. A figure from a web page would be read as permission. The geometry and the resistance are properties of the copper, and those it gives.
