Measuring Canvas for Framing
Canvas isn’t always square, so we recommend measuring at the top, middle, and bottom in both directions for the most accurate measurement. If these numbers vary, order a frame with the largest measurement to ensure the canvas fits. If the measurements vary by more than 1/4", a canvas float frame is recommended.
Be sure to include the additional canvas folded at the corners – not just the size of the stretcher bars. The folded canvas can add up to 1/8" to the measurement. Remember to also take the canvas depth into consideration. Select a frame with a rabbet depth – the inner portion of the frame that holds the canvas – that is deeper than the canvas stretcher bars.
Note: Rabbet depth of all our picture frames can be found on the frame detail page as the “R” measurement.
