Sorry I thought you would be able to read the sizes.
You need 2 A4 sheets.
All my instructions are in inches :c)
Cut one to 10.5 by 8.25 (width of normal A4)
Score at 0.5 and 1 along both long side to form the box bits
Score lines shown above from the left at 1.5, 2, 7, 7.5
Cut away the top and bottom section as in the pic
You will need another piece of card 5 by 6.25 to form the front.
Hope that helps
