Measuring and Layout — FAQ
Does DeWalt make a framing square?
As of 2026, DeWalt does not manufacture a dedicated framing square. They focus on speed squares and layout tools. The products we tested are the best alternatives that match DeWalt's job site durability and precision standards.
How do I check if my framing square is accurate?
Place the tongue (short leg) against a straight board edge. Draw a line along the blade (long leg). Flip the square over and draw a second line over the first. If the lines diverge, your square is off. Quality squares should match within 1/64" over 24".
What's the difference between a framing square and a speed square?
Framing squares (16"x24") are for large layout work—rafters, stairs, wall framing. Speed squares (7") are triangular guides for quick 90° and 45° marks and circular saw guides. Pros carry both: speed square for cuts, framing square for layout.
Can I use a framing square for metal framing?
Yes, but steel squares can scratch protective coatings on metal studs. Aluminum squares or those with polished edges work better. The scales and principles remain identical for wood or metal framing layout.
How do I maintain my framing square?
Wipe clean after each use to prevent concrete and pitch buildup. Store flat or hung vertically—never prop on an edge where it can bend. Occasionally rub edges with wax paper to maintain smooth sliding action during layout.
Why do some squares have octagon scales?
Octagon scales help layout eight-sided posts and timbers common in post-and-beam construction. While rarely used in modern stick framing, they're valuable for timber framers and restoration carpenters working with traditional joinery.
