About this activity

What you practise: You planned from the narrowest point, subtracted clearance on both sides and allowed for the edge strips, all before an irreversible cut.

You want a shelf to fit this opening. Which measurement do you plan with? You measured the opening for a shelf three times: 80.1 cm at the top, 80.0 cm in the middle and 79.8 cm at the bottom. The board has to pass the tightest point. At the bottom there are only 79.8 cm, so that is your limit.
