About the wood stock sizes
Only two common stock sizes (widths and thicknesses) are required for this project.
They are dressed or surfaced 100 mm x 50 mm (2″x4″) and 100 mm x 25 mm (1″x4″).
When 100 mm x 50 mm (2″x4″) wood is dressed or surfaced, the size becomes approximately 90 mm x 45 mm (1 ½”x 3 ½”) which is called the ‘actual size’.
When 100 mm x 25 mm (1″x4″) wood is dressed or surfaced, the size becomes approximately 90 mm x 20 mm (¾”x 3 ½”) which is called the ‘actual size’.
All the measurements referred to in this project are the ‘actual sizes’.
Use a wood that is suitable for exterior use.
Dimensions for this project are given in both metric and imperial. All measurements are given in millimeters first, followed by feet and/or inches in brackets ( ). The metric sizes are not an exact match to the equivalent imperial sizes. A chair built using the metric measurements will be approximately 1.6% smaller than a chair built using the imperial (ft and in) measurements. The imperial measurements are more suited to North America. The metric measurements are more suited to Australasia.
