Line and area measurements
Line and area layers have a Show measurements option in the layer ⋮ menu. Switch it on and selecting a feature labels each straight stretch with its length, plus the total length for a multi-part line, or the area and perimeter for a shape.
The labels update live as you draw or reshape a feature, so you can watch a boundary’s area change as you drag a corner, and they disappear when nothing is selected.
The setting is per layer, so a map can measure its parcels without labelling its roads.
How to try it
- Switch to a line or area layer and open its ⋮ menu.
- Turn on Show measurements.
- Select a feature, then press Update and drag a corner to watch the figures change.
Capturing and editing features in the User Guide covers this in full.
