How to measure
All sizes are internal. Measure the opening as Length × Width, with the third dimension being Depth (or height) — L × W × D.

Board grade guide
Our board codes combine a number and a letter (e.g., 2B, 3C).

• The number indicates paper weight/strength on our scale: 1 = strongest, 5 = lightest.

• The letter denotes flute profile: B flute ≈ 3 mm, C flute ≈ 5 mm.
