Frame Window Size refers to the dimensions of the visible opening within a frame or mat through which the artwork is displayed. Also commonly called the sight size, this measurement is typically slightly smaller than the actual artwork to ensure it stays securely in place and is properly supported along the edges.

Uses

Determines how much of the artwork will be visible once framed.
Guides precise mat cutting and placement to avoid obscuring important details of the artwork.
Assists in designing a balanced visual presentation by aligning artwork with the frame and mat proportions.
Important in custom framing to ensure a snug fit without slipping or shifting.
Used in gallery or museum settings to maintain consistent presentation standards across multiple works.

Best Practices

Always measure the artwork accurately before determining the frame window size.
Subtract a small margin (usually 1/8" to 1/4") from the artwork dimensions to ensure the piece fits securely behind the mat or frame lip.
Consider the artwork's medium and thickness when calculating the window size to prevent damage or buckling.
Use precise cutting tools (e.g., mat cutter or computer-controlled mat cutter) for clean, accurate window edges.
When using double mats, ensure the top mat window slightly overlaps the artwork to hold it in place, while allowing the lower mat's color to show through for visual depth.
