Thank you for your enquiry.
A3 is 297x420mm
You can use the custom mount builder to calculate the measurement you require.
You need to input the actual size of your image and this allows a 4mm over lap and give us the measurements of the aperture – (the cut-out part for the image)
You then enter the mount required and you can choose a single or double mount, alter the overlap, choose the colour etc.
Alternatively, you can contact the sales team on 0800 980 1123 or alternatively or email us at [email protected] and a member of the team will be happy to help.
