Expert Verdict Reviewed by the SuperArbor Pro Desk

A 7-inch square covers most common rafter pitch and seat-cut layouts; step up to a larger framing square only for wide stock. The continuous scribing notch makes repeat ripping marks fast and consistent. The die-cast aluminum body resists jobsite knocks better than thin stamped-steel squares.

Keep the square flat against the stock and your free hand clear of the saw path when marking and guiding cuts.
