Which size corresponds to a one piece baseboard?

• A. 7/16" thick by 2 1/4" wide
• B. 5/8" by 3 1/4" wide
• C. 3/4" by 4" wide
• D. 1/2" by 2" wide

Answer: (A)

One-piece baseboard is a single molding that runs along the wall from corner to corner without a separate cap or shoe molding. The standard profile for this setup is 7/16 inch thick and 2 1/4 inches tall. That thickness gives enough durability to resist small knocks and hold paint well, while the 2 1/4 inch height provides a balanced, unobtrusive look that fits under typical doors and windows and pairs well with most flooring heights. Because it’s a single piece, this size is chosen to cover the joint cleanly without needing extra pieces, which is why other, thicker or wider dimensions are associated with two-piece bases or more decorative, heavier installations.
