Siding Cost Per Square Foot by Material Type

Siding costs $3 to $15 per square foot installed in 2026, depending on material. Vinyl runs $3 to $7, engineered wood $6 to $10, fiber cement $8 to $13, and natural cedar $8 to $15. But the per-square-foot price is only part of the equation. Your actual project cost depends on how much wall area you’re covering, how many openings you subtract, and how much waste your layout creates.

The siding calculator handles the area math and converts your measurements into both square feet and siding squares so you can price materials accurately.

How Wall Area Drives Your Siding Budget

Siding is sold by the square foot or by the “square,” which equals 100 square feet. Your total cost starts with gross wall area, the combined surface of every exterior wall.

For a rectangular home that measures 40 feet long, 30 feet wide, with 9-foot walls:

Gross wall area = Perimeter × Wall height

Gross wall area = (40 + 30 + 40 + 30) × 9 = 1,260 sq ft

That’s 12.6 squares. At $5 per square foot for vinyl installed, the starting number is $6,300 before subtracting openings or adding waste.

Most homeowners underestimate wall area because they forget gable ends. A gable 30 feet wide and 6 feet tall at the peak adds 90 square feet (half the base times the height). Two gable ends add 180 square feet, nearly two extra squares of material and $900 more in vinyl.

Subtracting Doors and Windows

You don’t side over openings. Every window and door reduces your net siding area, and the savings add up fast on homes with lots of glass.

Common opening sizes to measure:

• Standard window (3 × 5 ft): 15 sq ft
• Picture window (5 × 4 ft): 20 sq ft
• Entry door (3 × 6.67 ft): 20 sq ft
• Sliding patio door (6 × 6.67 ft): 40 sq ft
• Garage door, single (9 × 7 ft): 63 sq ft
• Garage door, double (16 × 7 ft): 112 sq ft

For the same 1,260-square-foot house with 8 windows and 2 doors:

Opening area = (8 × 15) + (2 × 20) = 160 sq ft

Net wall area = 1,260 - 160 = 1,100 sq ft

That drops the project from 12.6 squares to 11 squares. At $5 per square foot, you just saved $800 in material. A double garage door on the front wall saves another 112 square feet, roughly $560 in vinyl.

Measure every opening, including basement egress windows and any cutouts larger than 2 square feet. The siding calculator handles this subtraction automatically once you enter your total opening area.

Waste Factor: Why You Order More Than You Measure

Installers cut siding to fit around corners, windows, and irregular wall sections. That cutting creates scrap. Standard waste allowance is 10% for straightforward walls and 15% for homes with many corners, dormers, or mixed angles.

For the 1,100-square-foot example at 10% waste:

Waste = 1,100 × 0.10 = 110 sq ft

Order quantity = 1,100 + 110 = 1,210 sq ft (12.1 squares)

Running short mid-project means a second order with a separate delivery fee, and dye lots may not match your first shipment. Ordering 10% extra is cheaper than a color mismatch on your most visible wall.

Board-and-batten and shake-style siding generate more scrap than standard lap siding because of varied piece sizes and vertical cuts. Budget 15% waste for these styles. Lap siding on a simple ranch with few corners can work with 7% to 10%.

Siding Cost Comparison by Material

Costs below are per square foot installed, including labor and basic trim. Prices reflect 2026 national averages.

Material	Cost per sq ft (installed)	Lifespan	Maintenance
Vinyl	$3 - $7	20 - 40 years	Low, wash annually
Engineered wood (LP SmartSide)	$6 - $10	25 - 50 years	Repaint every 10 - 15 years
Fiber cement (Hardie)	$8 - $13	30 - 50 years	Repaint every 10 - 15 years
Cedar / natural wood	$8 - $15	20 - 40 years	Stain or paint every 5 - 7 years
Brick veneer	$10 - $18	50+ years	Minimal

Vinyl is the most popular siding in the U.S. because of its low upfront cost and near-zero maintenance. It comes in profiles ranging from traditional clapboard to Dutch lap and board-and-batten. Thicker premium vinyl (0.046 inch and above) costs more but handles impact and temperature swings better than builder-grade panels.

Fiber cement (commonly sold as Hardie Plank) resists rot, fire, and insects better than wood or vinyl. It holds paint well and comes in smooth or wood-grain textures. Installers charge more because the planks are heavy and require carbide-tipped saw blades.

Engineered wood (LP SmartSide is the most common brand) costs less than fiber cement and looks more like real wood than vinyl. It’s lighter and easier to handle on site, which can shave $0.50 to $1 per square foot off labor compared to fiber cement.

Whole-Home Example: Pricing a 1,800 Sq Ft Ranch

A typical 1,800-square-foot ranch with 9-foot ceilings, a perimeter of 170 feet, two gable ends, 12 windows, and 3 doors:

Gross wall area = 170 × 9 = 1,530 sq ft

Gable area = 2 × (30 × 5 / 2) = 150 sq ft

Total gross area = 1,530 + 150 = 1,680 sq ft

Opening area = (12 × 15) + (3 × 20) = 240 sq ft

Net area = 1,680 - 240 = 1,440 sq ft

With 10% waste = 1,440 × 1.10 = 1,584 sq ft (15.84 squares)

Cost estimates for this project by material:

• Vinyl at $5/sq ft: $7,920
• Engineered wood at $8/sq ft: $12,672
• Fiber cement at $10/sq ft: $15,840
• Cedar at $12/sq ft: $19,008

These numbers cover material and installation only. The next two sections break down what adds to that baseline and how maintenance changes the math over time.

What Pushes Siding Cost Higher

Several factors increase cost beyond the base material and labor price:

• Story height. Two-story homes need scaffolding, adding $1 to $2 per square foot in labor. A two-story version of the ranch example above would add $1,500 to $3,000.
• Complex layouts. More corners, bump-outs, and dormers push cutting waste from 10% to 15% or higher.
• Removal of old siding. Tear-off adds $1 to $2 per square foot. Some contractors overlay new vinyl on old vinyl, but fiber cement and wood usually require a clean substrate.
• Insulation upgrades. Foam board behind new siding costs $1 to $2.50 per square foot but can cut heating bills 10% to 20%.
• Regional labor rates. Coastal and metro areas run 20% to 40% above Midwest and rural markets. A $5/sq ft vinyl job in Ohio might cost $7/sq ft in Connecticut.
• Timing. Siding crews stay busiest from May through September. Scheduling in late fall or early spring can knock 5% to 10% off labor because contractors want to keep crews working through the slow months.

20-Year Cost: Material Plus Maintenance

Upfront price alone doesn’t reflect what you’ll spend over the life of the siding. Cedar needs restaining every 5 to 7 years. Fiber cement and engineered wood need repainting roughly every 12 years. Vinyl just needs a pressure wash.

Here’s the 20-year picture for the 1,584-square-foot project above:

Material	Install cost	20-year maintenance	20-year total
Vinyl at $5/sq ft	$7,920	$500 - $1,000 (washing only)	$8,420 - $8,920
Engineered wood at $8/sq ft	$12,672	$4,000 - $6,000 (one repaint)	$16,672 - $18,672
Fiber cement at $10/sq ft	$15,840	$4,000 - $6,000 (one repaint)	$19,840 - $21,840
Cedar at $12/sq ft	$19,008	$8,000 - $14,000 (3 - 4 restains)	$27,008 - $33,008

Vinyl wins on pure cost. But fiber cement and engineered wood add more resale value. Industry data shows fiber cement recoups 70% to 80% of its cost at resale, compared to about 65% for vinyl. If you plan to sell within 10 years, the higher upfront spend on fiber cement often pays back at closing.

How to Budget Your Siding Project

Suppliers quote siding by the square (100 sq ft), by the piece, or by the linear foot depending on material. Vinyl panels typically ship in boxes covering 2 squares (200 sq ft). Fiber cement planks are sold individually, and coverage depends on plank width and exposure. The siding calculator converts your net area into both square feet and squares so you can compare quotes without manual conversions.

Follow this budgeting sequence:

1. Measure every wall section, including gables.
2. Subtract all window and door openings.
3. Add 10% to 15% for waste.
4. Multiply the total by your material’s cost per square foot.
5. Add $1 to $2 per square foot for tear-off if replacing old siding.
6. Get at least three contractor quotes and ask for line-item breakdowns separating material from labor.

One quoting trap to watch: a bid “per square” that already includes waste is very different from one based on net wall area where waste gets added separately. Confirm which method the contractor uses before comparing numbers. A $350/square quote with waste baked in and a $350/square quote on net area could differ by $500 to $1,000 on a full-house project.
