Timber, lumber. The hard fibrous lignified substance under the bark of trees sizes and measurements
All measurements throughout this project are given in both Standard/Imperial inches and Millimeter measurements. (Abbreviation for millimeter which is a metric unit of length equal to one thousandth of a meter. 25.4 mm equals one inch.).
The measurements are given first in inches followed by millimetres in brackets (mm).
The size (width and thickness) of the wood referred to throughout this project is the The rough-sawn size of a piece of lumber. Before the lumber is surfaced, planed or dressed. The nominal size is usually greater than the actual dimension. e.g. 100x50 (2 x 4) actually equals 90x45 (1 1/2" x 3 1/2")..
That is in reference to the size of the Any of the framing wood. before it has been Surfaced; planed; smooth; even surface; gauged. (See Dressed. planed and/or seasoned).
When the wood has been dressed, (surfaced planed and/or seasoned) it is then called the ‘actual size’ which is the true size.
The The finished (dressed) size as opposed to the nominal size of a piece of wood. of lumber is smaller than the nominal size.
For example, if you have a piece of wood (lets say a piece of 2 x 4) in its rough state (prior to being dressed)
its size will be just that, 2″ x 4″ (two inches thick by four inches wide). However, once it has been dressed (surfaced, planed and/or seasoned), the finished wood will measure approximately 1 1/2″ x 3 1/2″ which is the
‘actual’ size (one and a half inches thick by three and a half inches wide).
Most Countries that use the Metric system generally call the bigger numeral first such as 100mm x 50mm.
whereas those that use the Standard. Feet and inch measurements. system generally put the smaller numeral first such as 2″ x 4″.
Rough or dressed wood, how does it matter?
In the overall scheme of things, it doesn’t matter that much. Use either rough or dressed. Rough wood is usually cheaper but dressed wood is
easier to work with and paint. Just remember to make allowances for the size difference when working off the plan if you use dressed (actual size) wood.
Below is a ‘nominal’ versus ‘actual’ list with all the wood sizes used in this project.
Nominal size 2″ x 2″ vs Actual size 1 1/2″ x 1 1/2″
Nominal size 2″ x 3″ vs Actual size 1 1/2″ x 2 1/2″
Nominal size 2″ x 4″ vs Actual size 1 1/2″ x 3 1/2″
Nominal size 4″ x 4″ vs Actual size 3 1/2″ x 3 1/2″
Nominal size 1″ x 4″ vs Actual size 3/4″ x 3 1/2″
Nominal size 1″ x 6″ vs Actual size 3/4″ x 5 1/2″
Nominal size 1″ x 12″ vs Actual size 3/4″ x 11 1/4″
Nominal size 50mm x 50mm vs Actual size 45mm x 45mm
