Studs, joists, and rafters are always spaced 60 cm (23.62 in) on center. The dimensions of OBS and other sheets are multiples of 60 cm in both dimensions so they can be placed in either direction, e.g., 60 x 240, 60 x 300, or 120 x 300 cm. That’s smart to go with 60cm centers.

What is a 2×4 in Europe?

closest to 2×4 would be 50×100 mm (fives). We often used 40×80 (fours) for roof frames. EDIT: I just learned your “2x4s” are just a nominal size but their actual size is about 1,5 × ​3,5 inches or 38 × 89 mm.

What is a 2×4 called in England?

If you buy 4 x 2 PAR (Planed All Round), its the same stuff which has been put through a planer to smooth it off, generally its then about 3 3/4 x 1 3/4. The general term in the UK for wooden partitions is studwork, don’t ask me why, I just know it is.

What is the typical unit of measure for wall framing?

1. BOARD MEASURE – is the term to indicate that the board foot is the unit of measurement for most lumber items. A board foot is defined as a piece one inch thick (nominal) by one foot wide (nominal) by one foot long (actual) or its equivalent. For instance a 2 x 6 also equals one board foot for each foot of length.

How far apart are studs in Europe?

Studs, joists, and rafters are always spaced 60 cm (23.62 in) on center. The dimensions of OBS and other sheets are multiples of 60 cm in both dimensions so they can be placed in either direction, e.g., 60 x 240, 60 x 300, or 120 x 300 cm.

What is 2×4 wood in MM?





Nominal vs. Actual Measurements of Dimension Lumber

2 x 10 1 1/2 x 9 1/4 inches (38 x 235 mm)

What is the Australian equivalent of a 2×4?

This is similar to this question about metric measurements. In Australia, a common measurement is 90mm x 45mm for timber. A 4×2 would be (approx) 100mm x 50mm but, as I understand it, that is the milled rather than final measurement.

What is 4×2 timber in metric?

What size is 4×2 timber in mm? The most common way to express this size of treated timber is in inches (4×2). However, in metric, it is 47mm x 100mm or 50mm x 100mm.

Why is a 2×4 not a 2×4?

Now, most timber is milled and planed to give it a little more of a finished look, and a little more of a consistent size and profile. Because of this extra milling, a 2×4 no longer measures a full 2 inches by four inches.

What comes first length or width or height?



Measurements always go in the following order: length x width x height. For example, if a product is 12″ x 6″ x 8″, it is 12 inches long, 6 inches wide, and 8 inches tall. If there is a fourth number, that is for the depth or thickness of the item.

How do you measure frame size?

Measuring your frame



To measure the frame, lay it down on a flat surface face down. Remove any backing board, mounts and pictures. You will see the frame has a rebate your mounts and backing and glazing will fit on to. Measure the width and height of the internal size of the frame in mm (Fig 3 & 4).

How do you determine your frame size?

Body frame size is determined by a person’s wrist circumference in relation to their height. For example, a man whose height is over 5′ 5″ and wrist is 6″ would fall into the small-boned category.

How far apart are wall studs UK?



Studs are spaced evenly along the wall usually 16/24″ or 400/600mm. It is important to keep this spacing to a clean fraction of the plasterboard width, so that the edges of the board always fall on a stud without each board needing to be cut to fit.

How far apart are studs in a wall Australia?

450mm apart

Vertical studs are normally spaced 450mm apart, measuring centre to centre. If you are putting a doorway in the wall, leave a space that includes enough room for the door and the doorjamb. The distance between the top and bottom plates may vary slightly, so measure the length for each individual stud.

How is lumber measured in Canada?

Lumber can be referred to by its nominal size in inches, which means the actual size rounded up to the nearest inch or by its actual size in millimeters. For instance, 38 × 89 mm (1-1/2 × 3-1/2 in) material is referred to nominally as 2 × 4 lumber.

Is the metric system used in construction?



One metric unit is used to measure length, area, and volume in most design and construction work: – meter (m). – Use only the meter and millimeter in building design and construction. – Use the kilometer for long distances and the micrometer for precision measurements.

Why is dimensional lumber not actual size?

Maybe you’ve noticed that lumber sizes are often misleading. The “nominal” cross-section dimensions of a piece of lumber, such as 2 X 4 or 1 X 6, are always somewhat larger than the actual, or dressed, dimensions. The reason is that dressed lumber has been surfaced or planed smooth on four sides (called S4S).

Why do carpenters use the imperial system?

Because it’s not cost-effective to produce wood products to two standards, the U.S. standard ends up being the standard for pretty much all building materials manufactured in North America. Thus goes the materials-based theory of why most Canadian carpenters still work in inches and feet.

Why is imperial better than metric?

The basis of the argument is that while the metric system of units is based on scientific constants, the imperial system is based on the size of everyday items. From Real Clear Science: While the metric units’ association with physical constants makes them accurate, it makes them less practical for common use.

What’s more accurate metric or imperial?



Metric is simply a better system of units than imperial



The metric system is a consistent and coherent system of units. In other words, it fits together very well and calculations are easy because it is decimal. This is a big advantage for use in the home, education, industry and science.
