Clapboard vs Dutch Lap Siding: Differences, Cost & Style
Clapboard and Dutch lap are the two most popular horizontal siding profiles in America. Both run in overlapping horizontal rows, both come in vinyl, wood, and fiber cement, and both cost about the same. The difference is in the shape of each board, and that shape changes how the whole house looks.
TheRemodelers works with licensed siding contractors to help homeowners choose the right profile. This guide explains how clapboard and Dutch lap differ, which house styles suit each, what they cost, and how to decide. For every siding material and cost, start at our siding project hub.

What Clapboard Siding Is
Clapboard is the original lap siding: long horizontal boards, thicker at the bottom edge than the top, each overlapping the one below. In wood it is often called bevel siding. Each course casts a clean, straight shadow line.
Because it is simple, clapboard works on almost any house, from historic colonials to modern farmhouses. In vinyl it is often sold as "double 4" or "double 5," meaning each panel shows two courses at a 4- or 5-inch exposure.
What Dutch Lap Siding Is
Dutch lap adds a curved groove, or bevel, along the top of each course. That groove deepens the shadow line, so the wall reads as more textured and more traditional, like hand-cut boards. It is most common in vinyl, where the profile is molded in.
Dutch lap comes in similar exposures, such as double 4 and double 5. The deeper shadow can help hide minor waviness in an older wall.
Which Looks Better on Your House?
Choose clapboard for a clean, timeless look that suits nearly any style, or for modern farmhouse and contemporary homes where simple lines fit best.
Choose Dutch lap for more depth and shadow, especially on colonial, Victorian, and traditional homes, or to add texture to a large plain wall.
Match the neighborhood: on historic streets, the profile neighbors and HOAs expect may decide it for you.
Many homes combine profiles, such as clapboard on the main walls with board and batten or shakes in the gables. For current style and color trends, see our guide to siding styles and trends.
What They Cost
Clapboard and Dutch lap cost about the same in the same material and grade, so cost rarely decides between them. Material and thickness drive the price:
Material | Installed Cost per Sq Ft | Typical Home (≈1,800 sq ft of wall) |
|---|
Vinyl | $4 – $8 | $7,200 – $14,400 |
Engineered wood | $5 – $10 | $9,000 – $18,000 |
Fiber cement | $6 – $13 | $10,800 – $23,400 |
Natural wood | $8 – $15 | $14,400 – $27,000 |
In vinyl, thickness matters more than profile. Our vinyl siding guide explains the grades, and our wood siding guide covers clapboard in natural wood.
Maintenance Differences
The two profiles need about the same care, which depends mostly on the material. Vinyl needs an occasional wash, fiber cement and engineered wood need repainting about every 10 to 15 years, and painted wood every 5 to 10.
Dutch lap’s groove can collect a little more dirt and pollen, so it may need a slightly closer look when washing.

Final Thoughts
Clapboard gives a clean, classic line that suits almost any home. Dutch lap adds depth and a traditional, handcrafted feel. They cost about the same, so the choice comes down to the look you want, your home’s style, and the material you choose.
