Board feet are calculated using the formula: (Thickness in inches × Width in inches × Length in feet) ÷ 12. For example, a board that is 1 inch thick, 6 inches wide, and 8 feet long equals (1 × 6 × 8) ÷ 12 = 4 board feet.
A board foot is a unit of lumber volume equal to 144 cubic inches — equivalent to a piece of wood 1 inch thick, 12 inches wide, and 12 inches long. It is the standard measurement used by US lumber yards to price hardwood lumber.
A standard 2×4×8 contains approximately 5.33 board feet. Using nominal dimensions: (2 × 4 × 8) ÷ 12 = 5.33 BF. Note that actual milled dimensions are 1.5" × 3.5", but lumber yards typically bill based on nominal size.
Use a 10% waste factor for standard projects with straight cuts. Add 15% for projects with curves, joinery, or complex angles. Add 20% or more if you are a beginner or working with figured wood that may have more defects.
Lumber costs vary by species. Common pine averages $2.50 per board foot, while premium hardwoods like black walnut cost $8–$10 per board foot and exotic species like teak can reach $12–$15 per board foot. Prices vary by region and lumber grade.
Nominal dimensions are the name given to a board (e.g. 2×4), while actual dimensions are what it measures after milling (1.5" × 3.5"). Always measure your actual lumber when calculating board feet for a project rather than relying on nominal sizes.
A board foot is the standard unit of measurement for lumber volume in the United States. It represents a piece of wood that is 1 inch thick, 12 inches wide, and 12 inches long — totaling 144 cubic inches. Lumber yards use board feet to price hardwood lumber, making it essential for woodworkers to understand this measurement when planning projects and budgeting materials.
Thickness and width are measured in inches, length is measured in feet. The result is the total board feet for that piece of lumber.
| Project | Estimated Board Feet | Typical Wood |
|---|---|---|
| Small Bookshelf | 18-24 BF | Pine, Poplar |
| Coffee Table | 32-47 BF | Oak, Maple |
| Dining Table | 67-89 BF | Walnut, Cherry |
| Raised Garden Bed | 12-18 BF | Cedar, Redwood |
When purchasing lumber, you'll encounter nominal dimensions (the name of the board) and actual dimensions (the true size after milling). A 2×4 is nominally 2 inches by 4 inches, but the actual milled size is 1.5 inches by 3.5 inches. For accurate board foot calculations in your projects, always measure the actual dimensions of your lumber rather than relying on nominal sizes.
Professional woodworkers always add a waste factor to account for defects, mistakes, and offcuts. Use 10% for straightforward projects with simple cuts, 15% for projects involving curves or complex joinery, and 20% or more if you're a beginner or working with figured wood that may have hidden defects. This ensures you purchase enough material to complete your project without running short.
| Wood Species | Avg. Price per BF | Common Uses |
|---|---|---|
| Pine | $2.50 | Framing, shelving, outdoor projects |
| Cedar | $3.20 | Outdoor furniture, decking, siding |
| Poplar | $4.50 | Painted furniture, cabinets |
| Hard Maple | $5.80 | Cutting boards, flooring, furniture |
| Red Oak | $6.20 | Furniture, flooring, trim |
| White Oak | $7.50 | Fine furniture, barrels, outdoor projects |
| Cherry | $8.40 | Fine furniture, cabinets |
| Black Walnut | $9.80 | Premium furniture, gunstocks |
| Brazilian Walnut | $14.50 | Exotic furniture, high-end projects |

A cut list is a detailed list of every piece of wood needed for a woodworking project, showing the finished dimensions (thickness, width, and length) and quantity of each part. It is used to plan lumber purchases and organize cuts before building.
To make a cut list, identify every individual part in your project and write down its finished thickness, width, and length. Group parts by material type, then calculate how many boards or sheets you need to cut all parts with minimal waste. This tool automates that process instantly.
Saw kerf is the width of material removed by a saw blade with each cut — typically 1/8 inch for a table saw or circular saw. Kerf matters because each cut wastes a small amount of wood. On a project with many cuts, ignoring kerf can mean running short on material.
A cut list is simply the list of pieces needed. A cut list optimizer takes that list and calculates the most efficient arrangement of cuts on your available boards or sheets to minimize waste and reduce the number of boards you need to buy.
To calculate how many boards you need, add up the total length of all pieces required (accounting for saw kerf between cuts), then divide by your stock board length and add a 10% waste buffer. This tool calculates it automatically when you enter your pieces and stock board length.
Yes. The Sheet Goods tab handles plywood, MDF, OSB, and melamine. Enter the panels you need and your sheet size, and the tool will calculate how many sheets to buy and show a visual layout of how to arrange cuts on each sheet.
A cut list is a detailed inventory of every piece of wood required to build a woodworking project. It specifies the finished thickness, width, length, and quantity of each part. Every woodworker needs a cut list before heading to the lumber yard to ensure they buy exactly enough material without overspending or making multiple trips.
While a basic cut list tells you what pieces you need, a cut list optimizer tells you exactly how to cut them. An optimizer uses algorithms to arrange your required cuts onto your available stock boards or plywood sheets in the most efficient way possible. This minimizes scrap wood, reduces the total number of boards you need to purchase, and ultimately saves you money.
Saw kerf is the width of the material that is turned into sawdust by your blade during a cut. If you need 10 pieces from one board and each cut wastes 1/8 inch, that's 10 × 0.125 = 1.25 inches of wasted wood from kerf alone. If you don't account for kerf in your planning, your final pieces will end up too short.
The visual cut diagram shows each board or sheet you need to buy. The colored segments represent the pieces you need to cut, in the exact order you should cut them. The gray areas represent waste or offcuts. Use the pieces checklist below the diagrams to check off each part as you finish cutting it in the shop.
A cut list is a simple table of parts (e.g., 4 table legs, 2 aprons). A cut list optimizer is a tool that takes that table and maps it onto physical lumber. The optimizer does the complex math of fitting different sized pieces onto standard 8-foot boards or 4x8 sheets while accounting for blade kerf and grain direction.
