How To Figure Board Feet

Calculate the board footage of your board by entering the length, width, and thickness of your board. The board foot is the volume of one-foot length of a board one foot wide and one inch thick. This is done to avoid extra work of unloading the lumber on the scale and then loading it back. In general, using board feet is not always accurate when measuring uncut wood, because the way a board is processed affects the total volume of lumber, and the processing may differ greatly based on equipment and skill.

Also I might add, I’ve seen fellas use board feet as a term for pricing according to whats purchased. As the chart above shows, this board is actually 1-1/2 x 3-1/2 once the board is dried and milled into a plank and finished lumber. Figure the width of the stack as if the boards are butted up in a solid layer with no gaps. Most lumber yards will let you pick through their stock if you put back what you don’t buy.

When the board is first cut from the log, it is a true 2 x 4 but the drying process and planing of the board reduce it to a smaller finished 1.5 x 3.5 size. A simple way to figure how much you will need of the Slow Rise Foam is that the TF600SR kit will cover approximately 148sqft of wall at a 3.5″ stud depth. Note that when calculating board feet in terms of Thickness x Width x Length you should be using the rough thickness of the boards. If I gave away this much lumber in every beam I sold I would have been out of business 20 years ago.

I use this calculator often and find it handy, so I want to share it with any other woodworkers that need an easy to use board feet calculator. Since a tree is almost circular, use this formula to find the area of your tree at DBH (diameter at breast height). Once you have calculated the board feet of each piece of hardwood, add the amounts together to find the total board footage. Since the calculated board volume is in ftin2 instead of cubic inches, you cannot divide the volume by the amount of cubic inches per board foot (144 cubic inches).

Therefore, when considering measurements for lumber we have to keep in mind at what stage the volume of the lumber was measured. Open for retail sales of lumber and slabs from 8 a.m. – Noon on Saturdays and by appointment during the week. Board feet can be calculated by multiplying the thickness of a board(in inches) x the width of the board(in inches) x the length of the board(in inches) and then dividing the result by 144. Hardwood lumber is typically sold by the board foot, a unit of volume equivalent to a board that is one inch thick, one foot wide and one foot long, or 144 cubic inches.

All three of the scales estimate logs closely in the medium to larger size range, but the Doyle underestimates footage on the smaller logs. Volume of lumber also decreases as it dries, and the change in volume depends on the kind of lumber that is being processed, and can sometimes decrease by 30% or more. When calculating board feet, however, you should still use the actual measured number of inches for the sake of simplicity. In other words, 1-inch thick board would be expressed as four-quarter (4/4) board.

Unlike board feet, cubic feet or cubic meters are often used to measure entire logs including the parts that will later be discarded during processing, but excluding space between the logs if they are stacked, and often excluding the volume of the bark. For planed lumber, board-feet refer to the nominal thickness and width of lumber , calculated in principle on its size before drying and planing. You will still use the actual number of inches in your board feet calculation, though.

When a logger is willing to cut small volumes of salvageable sawtimber, landowners will normally have to accept a substantial reduction In price to compensate the logger for these additional costs. There is a board footage calculator, log volume calculator, tree value calculator and lumber and log weight calculator here. Therefore this measure is not as accurate because it depends on how well the logs are stacked, but this method provides a value that is easy, cheap, and fast to calculate — this is why it is popular.

When using this method of calculation, you need to know the length of the hardwood board in feet and not in inches. The total costs I figure based upon the specifics of the job at hand, where it’s slick finished or textured, how high the lids are, etc. When you purchase lumber, you may be surprised to find that a 2 x 4 board is NOT actually 2 inches thick by 4 inches wide in size.

Lumber thickness is expressed in quarters of an inch, beginning with 1 inch, so that 1 inch lumber is designated as 4/4, 1-1/2 inch lumber is 6/4, 2 inch lumber is 8/4, and so on. These units refer to nominal or roughsawn dimensions, not surfaced dimensions. Although there are other free board feet calculators – and I’ve tried them all – they either did not have all the options I needed, and/or had user interface quirks.

If this is rough-cut siding for board and batton, I would simply sell for my normal off-the-mill price plus any additional work encountered such as packaging, delivery etc. From style to tile, find tons of inspirational photos, ideas, and how-tos for brand-new rooms, quick upgrades, and big and small fixes, plus special offers. Using this method of calculation, you must know the length, width, and depth of each board in inches.

For example, the board feet for a standard 2 by 6 that’s 8 feet in length would be calculated as BF = (2x6x96)/144, or 8 board feet. The percentage of clear wood required for each grade is based on the surface measure, not the board feet, and because of this all boards, no matter what the thickness, are graded in the same way. I understood the questioner was trying to find a method of tallying without the use of a grading stick. He has the same complaints, except the blames the mill for cutting back on the useable board feet.

A 600 board foot kit is almost the same price as 2 of the 200s, so buying a large 600 kit is 30% free product over buying 2 of the 200 bd. ft. kits. Therefore, portable sawmills can provide landowners with a readily available supply of lumber that may be worth two to three times the cost of sawing. Use the same stiff tape measure to measure the width and depth of the same board.

To prove it to yourself, call several sawmills/lumberyards and ask them to calculate the same piece of wood and record the results. The interesting part of this process is that you don’t really need to be concerned with board feet. The end results are: The $2.20 price is actually cheaper than the $2.00 price due to the Tally method used! Once I figure that out, all I’m adding is 20% for the kerf of my table saw blade. We will walk away from the tree until point A, noting the distance from A to B, and then find the angle A using a protractor or similar tools.

Find out which one your mill uses, and then go online and print out the Table for that scale. For example, the actual size of a 4 inches by 6 inches board is 3.5 inches by 5.5 inches. Straight logs, with little taper and cut on a thin-kerf bandsaw will yield more lumber than the scale predicts. In the chart below (at the bottom of the page), we translate common or nominal” or true” board sizes into board feet measurements.

And furthermore, it makes it much easier to select that perfect wood grain while you are at the lumber yard. Also make sure you know exactly what they are sending, in terms of general board length and width. Scale tables tell you the approximate amount of lumber in a log, not the amount of wood. The dude asked for a way to mathematically figure board feet of a ten foot log. Dimensional construction lumber is sold by the lineal foot for a given size 2×4, 4×6,.. Home Cheapo sells precut 2×4 studs by the stick. During this part of the calculation, you are actually determining the volume of the board.

Your teacher may have already measured and calculated board footage for the trees. To determine how many, find the measurements of the areas you plan to drywall and round those total areas to the nearest foot. And beyond what you’ve mentioned, I have boughten one inch lumber that was planed down to make one half inch lumber. The definition is rather simple, one board foot is a piece of lumber that is 1 foot wide, 1 foot long and 1 inch thick, or its volumetric equivalent. Example: Calculate board feet for 2.17 feet of five-quarter (5/4) hardwood measuring 4.5 inches wide. For example, if a board is 1′ wide and 10′ long, it will cover 10 square feet of area.

Board foot is a unit generally used in the USA and Canada for uncut wood, but with the assumption that the wood is cut into boards of specified height and width, determined by the selected rule. When you’re looking at a stack of hardwood lumber and and you begin picking out the boards you like and want to buy, you’ll notice that each board has a different width (W), and possibly a different length (L).

To determine surface measure, multiply the width of the board in inches by the length of the board in feet and divide the sum by 12 rounding up or down to the nearest whole number. The Board Feet Easy Calculator is a simple, and easy to use, application for calculating board feet. Forests are managed for recreation, watershed protection, animal habitats, and for products such as paper and lumber. Measuring the hardwood board yourself is always recommended when possible, though. The last time I bought 800 board feet, I checked their calculations against my calculations. The first piece is 4.3 board feet, the second is 6.8 board feet, and the third is an even 2 board feet.
