About Frame Size Lab
Independent dimension tools for pictures, photos, posters and mats.
Frame Size Lab is an independent reference project operated by Noah Levy. It helps you compare dimensions before you choose a frame or plan a decorative arrangement.
Our tools separate full artwork size, mat-window size, nominal frame opening and outside frame dimensions. They combine published reference dimensions with original arithmetic and proportional diagrams.
Editorial approach
We cite the sources used, label manufacturer-specific conventions and publish a reviewed date. We do not claim professional framing certification, physical product testing or universal fit. Review our methodology and source register.
Funding
The launch site has no active affiliate links or display ads. Future commercial relationships must be disclosed near the relevant links. Revenue opportunities do not determine calculator results.
