How Much Lumber Do I Need for a Cutting Board?

Well, producing a cutting board is an effective woodworking project, although finding out the right amount of lumber needed for the production of a cutting board is challenging, especially when using rough boards or different kinds of wood. This will depend on the dimensions of the cutting board, its thickness, the design, and the waste material after cutting.

So, it is always important to have an estimation of the right amount of material needed to ensure that you do not spend money unnecessarily in purchasing extra materials. A board foot calculator helps you to calculate the exact volume of lumber you need for your woodworking projects.

What Determines the Amount of Lumber You Need?

You may want to know: What factors influence the lumber requirement?

So, you have to determine the finished measurements of your cutting board before buying your lumber. For example, an 18-inch by 12-inch by 1.5-inch size is fairly common, but there is no limit to how you can make your cutting board because they vary in shapes and sizes.

Some factors that influence your calculation for your lumber include:

• Finished length and width
• Desired thickness
• Patterns and designs for your board
• Species of wood
• Waste from cutting and milling
• The number of boards or strips

In the end, end-grain cutting boards use more lumber because you need to cut your lumber and arrange it according to patterns.

How to Calculate Lumber for a Cutting Board?

First, calculate the approximate volume of your finished cutting board.

Let’s consider a cutting board of dimensions 18 × 12 × 1.5 inches. The volume of the cutting board will be equal to:

18 × 12 × 1.5 = 324 cubic inches

But, since one board foot is equal to 144 cubic inches,

324 ÷ 144 = 2.25 board feet

This is the approximate volume of your finished cutting board, but you should not purchase 2.25 board feet of rough lumber because of woodworking wastage.

Account for Woodworking Waste:

Well, unfinished wood needs milling, jointing, ripping, cross-cutting, and sanding. Each of these processes can account for material waste.

Remember, when making an edge grain cutting board, it would be helpful to buy 20% to 30% more lumber than the end product volume. End grain projects may need a bigger percentage allowance since they will have many cuts and gluing operations.

For instance, when the project calls for approximately 2.25 board feet, getting an extra 2.7 to 3 board feet will do just fine.

Choosing Lumber for a Cutting Board:

Well, it is important to know that not all woods are good for making a cutting board. Usually, people use hardwoods with the right properties of wood grain.

They are:

• Maple
• Walnut
• Cherry
• Beech
• Oak

Quick insight:

• Do not use wood that is not suitable for use in contact with food.
• Do not forget to look at the condition of the wood and dry it out before starting work.
• If you need to use different woods, calculate how much wood of each kind you will need. It will help you make a color pattern.

Board Feet vs. Linear Feet

Well, the board feet calculator measures the volume of lumber based on three parameters – thickness, width, and length. This is what makes board feet an applicable measuring unit for buying hardwood from a lumber company.

On the other hand, the linear foot calculator measures the length only and can be helpful if you buy strips of lumber, but it does not take into account different lumber thicknesses and widths.

In addition to that, there is a Log Board Foot Calculator which allows calculating how much lumber can be extracted from logs prior to lumbering.

To conclude, in the case of a cutting board project, board feet will be more applicable.

Why Should You Buy Extra Lumber?

Well, the proper amount of waste depends on your project. Think about purchasing additional lumber for:

• Milling & Surfacing
• Defects & Knots
• Cutting errors
• Pattern Matching
• Adjusting sizes
• Sanding & Finishing

To conclude, for your first time cutting a board, having that little bit of extra wood could take the stress out of the project. Additionally, experienced woodworkers are able to cut down on their waste by creating a cut pattern prior to purchasing lumber.

Conclusion:

Wrapping up, the volume of lumber necessary for a cutting board depends on its dimensions, construction type, wood species, and expected waste. First of all, calculate the finished volume and then take into account the extra volume necessary for milling and cutting. For any hardwood projects, a board foot calculator helps in estimating the accurate volume of lumber.

Frequently Asked Questions (FAQs)

How much lumber is needed for an 18×12 cutting board?

The volume of a finished 18×12×1.5-inch cutting board is approximately equal to 2.25 board feet.  However, to estimate lumber for an 18×12 cutting board, we should take into account the extra volume for milling, cutting, and waste.

How much additional wood is necessary for a cutting board?

When calculating the volume of lumber for a cutting board with waste, it would be wise to purchase 20% to 30% more material than the finished volume. End grain projects will require additional volume due to more complicated construction.

Is it possible to use a board foot calculator for a cutting board?

Yes, you can use a board foot calculator for estimating the volume of hardwood for a cutting board lumber project. It is also recommended to calculate each wood species separately when making a multi-colored or patterned board.
