Wood sizes and measurements
The wood sizes – bit of an explanation
Note: The wood sizes mentioned below are the stock sizes I was able to source locally. Sizes could vary from place to place. A slightly bigger or smaller stock size (within reason) will fare just as well.
There are only two different wood sizes used for this project. They are ex 1 1/2″ x 3″ (38mm x 75mm) for the two side frames and ex 1″ x 3″ (25mm x 75mm) for the seat slats and backrest slats.
Note: The term ‘wood size’ refers to the width and thickness of the wood, not the length. There are a number of different lengths.
The term ‘ex’ (as mentioned just before the wood sizes in the first paragraph) means ‘out of’.
When the wood is planed or dressed ‘out of’ the sizes mentioned following the ‘ex’ (the nominal size), the finished wood size will then be somewhat less (the actual size).
The nominal vs actual size of the wood:
Nominal size (unplaned/undressed) – 1 1/2″ x 3″ (38mm x 75mm),
Actual size (when planed/dressed) 1 1/4″ x 2 3/4″ (32mm x 69mm).
Nominal size (unplaned/undressed) – 1″ x 3″ (25mm x 75mm).
Actual size (when planed/dressed) 3/4″ x 2 3/4″ (20mm x 69mm).
Note: It is the ‘actual size’ or ‘true size’ that will be referred to throughout this project.
‘Actual sizes’ can vary from place to place and country to country. If you cannot source the exact stock sizes as mentioned in this project, near enough is good enough. A slightly bigger or smaller stock size (within reason) will fare just as well.
About the measurements given
All measurements throughout this documentation are given in both standard (inches) and metric (millimetres).
The inches are given first followed by the millimetres in brackets.
For example: 3/4″ x 2 3/4″ (20mm x 69mm).
As far as the lengths go, the metric sizes are not an exact match to the equivalent standard sizes.
A bench built using the given metric measurements will be approximately 1.6% smaller than a bench built using the standard (ft and in) measurements. Hardly worth worrying about.
The measurements are rounded for practical purposes.
Basically what that means is, use one system or the other (not both together) and you shouldn’t have a problem.
