Tools
One measurement in, one kit size out, with the arithmetic shown rather than hidden.
The rule this uses is that you leave about 150mm of deck beyond the work zone on every open side, so you are never standing half on and half off. How to take the measurement explains why, and how to take it properly.
Work out the size
This is the whole of the logic the calculator runs. It is published as a table so you can check it, quote it or use it without the widget.
| Working length | Deck needed, both ends open | Kit size | Typical position |
|---|---|---|---|
| Up to 82 cm | Up to 112 cm | 112 x 112 cm | One spot: a vice, a pillar drill, a QC bench, a single machine. |
| 83 to 128 cm | 113 to 158 cm | 158 x 112 cm | One person stepping along a bench between a vice and a grinder. |
| 129 to 219 cm | 159 to 249 cm | 249 x 112 cm | A full bench run, a welding bay, or two people at one position. |
| 220 cm and over | 250 cm and over | Two or more 249 x 112 cm kits | A full bench run or a multi-position cell. |
Deck needed is the working length plus 15cm for each open end. An end against a wall, a machine base or another bench is not an open end.
Depth does not appear in the table because it never decides anything. Every kit is 112cm deep, and a standing position at a bench needs about 60 to 70cm of that.
What your floor does decides the surface, and that is a different three questions.
