To help cutting a card matte when mounting your prints

For a tutorial on cutting a card matte look at https://www.youtube.com/watch?v=vVhXkfk91rw.

The assumption is you will use millimetres though you are free to use whatever units you prefer.

Enter the actual size of the mount board in the BOARD WIDTH and BOARD HEIGHT fields below (the common default sizes are already in).

Enter the actual size of the print image in the PRINT WIDTH and PRINT HEIGHT fields below.

Set the PRINT MARGIN field (positive numbers give a white margin, negative numbers overlap the image, 4-5mm is usually a suitable amount).

Then select a vertical offset. The form will calculate a suitable offset although you are free to set your own or not.

The measurements will appear on the diagram at the bottom.
