Lumber Planning Calculators

Board-foot, square-foot, and linear-foot examples for planning. Quote quantities come from a species planner or quote form.

Project square footage plans coverage. Installed face comes from the selected product. Linear feet and piece count describe the wood. The sales unit is what Timberline quotes: usually LF for lumber and tropical decking, square feet or linear feet for verified flooring, SF for bark, and each/package for hardware. These on-page tools do not add cart or quote lines.

Board Foot Calculator

Calculates board feet (BF) from thickness, width, length, and piece count. It does not set a quote quantity. Use a species planner for the selected product’s coverage and quote units.

Board Feet = (Thickness in × Width in × Length ft) ÷ 12

Square Feet to Linear Feet

Converts a project area to lineal feet using an example face width. The result is a planning length, not a cart or quote line. For Ipe and other products with confirmed installed coverage, use the species planner.

Lineal Feet = (Square Feet × 12) ÷ Face Width in

Waste Allowance (planning)

Adds a selected planning allowance to a quantity you already have. It is not a required percentage and does not change the product’s sales unit.

Sales units

Most lumber, siding, paneling, trim, and decking wood: LF. Square footage and piece counts plan coverage. They are not the sell quantity.

Flooring: SF OR LF. Verified flooring products may be quoted in square feet or linear feet. The available units and conversion come from the selected product.

Bark siding: SF. Coverage is planned and sold in square feet for approved bark products.

Roofing: SF OR SQ. Approved roofing is sold by square foot or by square, matching the product record.

Hardware and accessories: EA. Clips, screws, bits, and similar items stay each or package.

Items that need confirmation: CONFIRM. Keep the catalog unit until Timberline confirms it.

Calculator FAQ

Do these calculators add items to my cart?

No. They only display an example result. Cart and quote lines must go through a species planner or quote form that uses the sales-unit policy.

When should I use a species planner instead?

Use a species planner for product-specific coverage, quote quantities, or a timber member list. Planners are available for Ipe, Cumaru, Garapa, Eastern White Pine, Cedar, Cypress, Arkansas Yellow Pine, Douglas Fir, and bark siding. Where installed coverage is unconfirmed, enter the requested quantity or ask our team for help.

Is square footage the sales unit for decking?

Usually not. Square footage plans coverage. Most decking wood is sold in linear feet. Verified flooring products may be quoted in square feet or linear feet. Bark remains square-foot based.
