Fitovers Sizing Guides

HOW TO USE:  Print the sizing guide document at 100% scale.  Place your glasses face down on the images of each size.  If your glasses fit inside the red guideline box, then that size will appropriately fit over your prescription eyewear.   If the width or height of your glasses extends outside of the red box, then you will need to try the next larger size.

IMPORTANT: The fitovers sizing guides MUST be printed at 100% actual size, or it will not provide an accurate recommendation of the size that fits over your glasses. It is important to set your print preferences with the scaling option turned off. This will ensure that the document prints at full size. Use the image of the coin on the printed sizing guide to verify it printed at 100%. The image should be the same size as an actual one pound coin and should measure 23.25 mm in diameter.
