Q&A for How to Calculate Linear Feet

There is no specific relationship between square footage and linear footage. It depends on the width of the pieces of material being used in the project.

There is no difference between feet and linear (lineal) feet if you're talking about length.

It depends on the width of whatever you're going to put on the floor. For example, if you're going to lay a roll of vinyl, you would divide the width of the roll into the area of the floor to get the linear feet of vinyl required.

It depends on the width of the vinyl. If you divide the width of the room by the width of the vinyl, that will give you the number of vinyl pieces you'll need to cover the floor. Multiply that number by the length of the floor. That's your linear footage of vinyl.

It depends on the width of the carpet. If it's at least four feet wide, you would need 14 linear feet. If it's not that wide, you'd need more linear feet.

You need 21 linear feet of carpet. Multiply 18x14 to calculate the square footage of the room, and then divide by the width of the roll (12 ft.). 18x14=252. 252/12=21. You need 21 feet. You should probably get some extra to allow for possible waste.

If you're talking about 5/8" rebar, the linear length is 16 ft.

The five "shelves" are each six feet long. That's where the 6 comes from. The shelves are made from 1 x 12 (not 112) boards. So the total linear footage of the 1 x 12 boards is found by multiplying 5 (boards) by 6 (feet) which equals 30 linear feet.

Take the width of the vinyl sheet and divide it into the area to be covered.

One tile is 3 inches wide and 6 inches long. If you put two of them together end to end, it will be 3 inches wide and a foot long. To make 70 linear feet, 3 inches wide, you need 140 (70x2) tiles. You don't say how wide you want the tiling to be.

You would need to know the square footage of whatever you're making, and then divide that by the average width of a finished row.

The equipment doesn't take up linear feet, it takes up square feet.

It depends on the width of the material you are using. I assume that the 24" is the standard size that they sell countertop material. Therefore, you just need the number of feet in 350 inches. Divide 350 by 12, to get 350/12=29 feet 2 inches. If you must buy in full linear feet, then you need at least 30 linear feet for your project.

96 linear feet.

Because different building materials come in different widths. You must take into consideration the material's width before you can determine how much length you'll need.

Each decimal point signifies 1/100 of a foot.

Assuming you'd be using concrete or asphalt paving (or even gravel), you will want to calculate the volume of paving material required (length by width by depth), rather than linear feet.

This will depend on the shape of the land. The 2.11 acres is the area, but for a fence, you need to know the perimeter. You need to measure the distance around the plot. You can either do this by physically measuring it, or get a land plot from the registry of deeds, for example, and see if it provides the information.

The 10x15 are the dimensions of the floor. I assume you mean to paint the walls, not the floor. Therefore, you also need the height of the walls, which you don't provide. To find the total square footage of the four walls, add the perimeter of the room (10+15+10+15=50) and multiply by the height. This will give you the total square footage of the four walls. If we assume the height is 8 feet (for example), then the square footage of the four walls is 50x8=400 square feet. You then need to check the can of paint (or ask a salesperson) to find out how many square feet one gallon is expected to cover. This is different for every kind of paint. If you want to paint the ceiling also, the area of the ceiling is 10x15=150 square feet.

First calculate the total area that needs to be sided. Divide that by the width of a piece of siding. That gives you the total length of the siding pieces needed.

Yes, it is. However, it also involves a width associated with a specific building material (such as a board of a given width).

Linear feet is a measurement related only to building materials.

The way it works is this: First you calculate the total area to be covered. Then you pick a covering material of known width. Then you divide the area by the covering material's width. That tells you how much length of material to procure.

As explained in the article above, linear footage is a measurement of materials such as wood, carpeting, flooring, wallboard, or wallpaper -- anything that comes in particular widths. It is not a general measurement of area. In the case of footings, concrete does not have a linear footage value associated with it. It is measured in cubic volume.

An "area" does not have any linear footage per se. If you're asking about the total linear footage of (for example) the boards needed to construct a floor or a deck, it depends on the width of the boards being used. For ease of computation, let's say you're using 2x6 planks. Assuming you're going to lay all the planks in the same direction, you would measure the length of the area in that direction, then multiply that by the area's width multiplied by two (because each board is one-half foot in width). That amounts to multiplying the area's length by the number of boards being used, which gives you the total (linear) footage of the boards required.

If you're asking about curtain material, for a curtain wall you would just multiply the height of the wall by the number of material widths you'll use. (So if the material is three feet wide, you would divide the width of the wall by three to find the number of material pieces you'd need.) You then multiply that by the height of the wall. That's the linear footage of material you'll need (allowing extra material for seams and waste). The linear feet of material you'd need to cover the windows depends on the width of the windows and the width of the material, and that's a bit too complicated to describe here.

It depends on the thickness of the rug.

The pool's perimeter measures 18 + 18 + 30 + 30 = 96 feet. The border tiles are exactly 1 foot wide. Assuming the tile border goes all the way around the pool, you'll use 96 tiles if you allow no space between tiles.

If you mean a 4"x4" beam 34' long, it is 34 lineal (linear) feet in length. As a practical matter, beams are not measured in linear feet, just in feet (or meters).

Because a road is covered by asphalt or concrete, the term "linear feet" does not pertain here. It's likely that you would need to know the "square feet" or even the "cubic feet" for such a project. Square feet would be (40')(460') = 18,400 sq ft. The cubic footage would depend on the depth of the concrete or asphalt poured.
