How to measure artwork for a frame
Measure artwork, visible area, thickness and tolerance before ordering a frame. This guide moves from measurement to a decision you can verify immediately with OprawTo tools. It does not assume a professional workshop and highlights situations where a framing specialist is the safer choice.
Key answer
Measure artwork, visible area, thickness and tolerance before ordering a frame.
Open the calculatorWhat to establish before calculating
- Record dimensions to the nearest millimetre, but do not claim more accuracy than your measuring tool provides.
- Keep artwork size, visible area and the frame rebate size as three separate values.
- Take a second independent measurement and record the allowance before ordering materials.
Step-by-step process
- Identify the artwork medium, actual size and details that must remain visible.
- Choose a framing route: no mat, one mat or a layered mat arrangement.
- Calculate window, margins, frame size and hanging point with the matching tools.
- Check cost, weight and cleaning requirements before approving the option.
- Save a project card and retain the measurements before cutting materials.
Practical example
Example: a 30 × 40 cm artwork in a 50 × 60 cm frame cannot be planned by subtraction alone. Mat overlap, a weighted bottom and the frame tolerance all change the result. Use the mat calculator and verify it against the physical frame.
Limits and artwork safety
Do not attach valuable artwork with packing tape, contact adhesive or directly to a board of unknown composition. The calculator cannot assess acidity or the physical condition of the artwork.
Frequently asked questions
Can I send the result to a framer?
Yes. Save the project and download the report, but mark which dimensions were measured and which were assumed.
Does a 1 mm difference matter?
It can matter with a tight window or hand cutting. Use a controlled allowance rather than forcing the fit.
Does one rule work for every medium?
No. Photographs, watercolours, embroidery and posters differ in stiffness, moisture sensitivity and mounting method.
