Design Tools is a simple utility for designers, providing key information quickly, precisely and with no unnecessary hassle.

Includes 5 handy tools for designers on the go:

- Paper sizes - including ISO, USA, photo, billboard and more.

- Digital Sizes - common web sizes, iOS and Video.

- Colour Converter - easily convert between RGB / HSL / HEX, with numerical values or our convenient colour picker.

- Unit Converter - conversion between pixel / inch / millimetre / point, with the ability to add custom dpi values.

- Golden Ratio Calculator - quickly and easily get relevant values based on the Golden Ratio.

Design Tools is optimised for quick and simple referencing, helping you to double check all those values that have to get right! We built this app from our experience as designers, and tried to include tools that would make our everyday working lives that little bit easier.

If you have any problems, suggestions or feedback, we would love to hear from you at Thanks for reading, and we hope you like it!
