Is there an option where the customer can type in a specific measurement and then I can put a price on it automatically depending what range the measurement is in? For example 10cmx10cm =£1 20cmx20cm =£2 30cmx20cm=£2.50
Any help would be appreciated 
Hi Charlotte, this is currently a feature request.

@charlotte I’m almost done with a configurator that does exactly that
Checkout https://www.bowud.com/the-configurator (still work in progress at the moment)
If you select all the options (essence, mesure, finition and fixation) it output a price and enable the add to product cart button
Would that be a solution for your project?
That would be ideal. When are you planning on finishing it? Also would you be able to let me use it for my website? I might change a slight bit of it but looks great! Thank you so much
