Picture Mounts - Measuring Advice

How to measure your artwork/photo for a picture mount (without a frame) in our design studio.

When you use our picture mount application in our design studio you will find help buttons to guide you through each step of the ordering process. Please click on the help buttons if you need help along the way.

You will notice that we will cut your mount to your exact specifications in millimeters so please follow these guidelines to help you measure your outside dimensions and aperture size correctly.

Outside dimensions.

If you already have a frame and just require a mount make sure you measure the inside measurements at the back of the frame, or the glass size. These are the sizes you would enter for the outside dimensions of your mount.

If you don't have a frame and just require a mount it is up to you to decide the outside size of your mount.

Tip: If you already have a frame and it has flexible tabs on the back we would suggest you make an allowance of 3 millimetres so the mount fits past the flexible tabs at the back of the frame.  For example, if your inside frame measurements are exactly 400 millimetres by 500 millimetres, your outside mount dimensions should be 397 millimetres by 497 millimetres so your mounts fits past the flexible tabs with ease.

Tip: To convert inches to millimeters simply multiply by 25.4. For instance 20inches would be 20 x 25.4 = 508mm.
24.5inches would be 24.5 x 25.4 = 622mm. Don't worry about anything after the decimal point when doing your calculation.

Inside dimensions / aperture size.

We will cut your mount to the exact sizes you specify so you need to make your aperture size slightly smaller than your image (otherwise your image will fall through the aperture).  We recommend that you measure the width and height of your image in millimetres and then subtract 6 millimetres from both dimensions.

For example, if your image measures 300 millimetres by 400 millimetres, your aperture size would be 294 millimetres by 394 millimetres. You would then enter these sizes for your aperture dimension.

Tip: If your image is quite large we would suggest you subtract 10mm from both dimensions so your image sits comfortably behind the mount aperture.

Important points to note:

1. Always use a proper ruler or a metal tape measure to measure your work for the most acurate results.
2. When ordering a mount to fit a frame you already have you must measure the INTERNAL measurements of the frame and order your mount size accordingly so the mount fits inside the rebate of the frame.

3. Always double check your sizes in the checkout before proceeding with your order.
