The strongest joint between the drawer front side and back is which joint?

• A. Butt Joint
• B. Dovetail
• C. Mortise and Tenon
• D. Dado

Answer: (D)

The strongest way to join the drawer front, side, and back is a dado-style joint, because it creates a large, square seating for the back panel and provides substantial glue surface along the full height of the side. This capture keeps the back firmly aligned with the sides and resists pulling apart when the drawer is opened and loaded.

A butt joint would offer very little glue surface and is weaker in resisting tension. A dovetail is extremely strong for end-to-end connections, but it’s not the typical method used to join the back to the sides in a standard drawer. Mortise and tenon is strong, but more work for this application and not as efficient as a dado for capturing the back panel. The dado effectively combines alignment with strength in this context.
