Let’s talk about the measurements used

The measurements throughout this project are given in both metricMillimeter measurements. (mmAbbreviation for millimeter which is a metric unit of length equal to one thousandth of a meter. 25.4 mm equals one inch.) and standard imperialStandard. Feet and inch measurements. (inches).
The metric measurements are given first, followed by the standard measurements in brackets ().
Please note that, for rounding off purposes, the metric (mm) measurements given do not convert exactly to their corresponding standard (inch) equivalents, so just choose one or the other and you won’t have any problems as far as the measurements go.
The standard measurements are best suited to North America and the metric measurements are best suited to Australasia and some other countries.

Let’s talk about the wood and sizes

The frame: I used treatedPressure treated. Refers to lumber that is treated in such a way that the sealer is forced into the pores of the wood. Refers to lumber pressure sprayed with chemicals to lengthen its life expectancy for outside use or inground applications. pine (suitable for exterior use) for the frame with a stock size of 32 mm x 64 mm (1 1/4″ x 2 1/2″).
That means that the wood is 32 mm (1 1/4″) thick, and 64 mm ( 2 1/2″) wide.

If you are unable to source that stock size, or unable to obtain it by other means (e.g. by ripping it down from a bigger stock size), then use a thicker wood. However, if you do this you will also have to change the length of the bolts to suit, as well as the length of the longer seat panelA sheet that forms a distinct flat and rectangular section or component. A transparent panel used to fill a framed section of a window. and the tabletop panel in relation to the shorter seat panel. See Step 8 for more information about that.

The seat and tabletop panels: I used 140 mm (5 1/2) wide x 19 mm (3/4″) thick, tongue and grooveA joint in which a protrusion (tongue) that runs along the edge of a board fits into a matching groove that runs along the edge of another board. Boards shaped with a tongue on one edge and a groove on the other so that they can be fitted together without gaps. boards for the seats and tabletop. Tongue and groove boards have a groove along one edge and a tongue along the other edge.
The tongue on one boardA piece of sawn, or dressed lumber of greater width than thickness. Usually 19mm (3/4") to 38mm (1 1/2") thick and 75mm (3") or more wide. fits snugly into a groove in another board.
Tongue and groove joints allow two or more boards to be strongly joined together to make a single flat surface.

Alternative stock: There are other alternatives, such as standard boards or decking boards. They will be dealt with in the appropriate step. Standard 90 mm (3 1/2″) wide x 19 mm (3/4″) thick boards (as another option) will be allowed for in the materials (shopping) list as well as in the plans in Step 8.
