The best dimensions for panel inserts are ¼ inch thick and sized to leave a 1⁄16 to 1⁄8 inch expansion gap on all sides within the frame groove. This allows seasonal wood movement and prevents cracking. Width and height should match the frame opening minus the total expansion gap.
Typical sizes, such as 0.260" diameter for round inserts in Spaceballs SPACEBALLS-1000PK, ensure a snug fit in 1/4" grooves. Rectangular inserts like those in Midcoast PB265-750XF-10M are sized at .265" x .265" x 3/4" for similar grooves, offering stability and preventing rolling. With various dimensions available, you can find an insert that fits your specific panel requirements.
