How can I record an item's measurements so buyers know exactly what was measured?
Quick answer
Write each measurement as a labeled dimension with a unit, such as “width: 12 cm.” State the item's orientation and where the measurement begins and ends—for example, the widest outside points, edge to edge. For curved or irregular items, name the path or section measured and note that method. Keep measurements separate from estimates, and use placeholders until you have actually measured the item.
The question, the details, the next step.
A practical checklist
Choose and state the item's orientation for the measurements.
Give every number a dimension label and unit.
Name the start and end points, edges, or path for each measurement.
Say whether notable projections or features are included or excluded.
Identify maximum spans or varying sections when one number could be misleading.
Mark measurements as approximate when appropriate, and use only figures actually measured.
A few more useful answers
Should I use centimetres or inches?
Choose a unit system and label every value. If you provide a converted value as well, label that unit too and keep the stated precision appropriate to the measurement.
Is “overall dimensions” enough?
Usually not by itself. Pair it with labeled dimensions and a short explanation of orientation and endpoints so readers can tell what each figure represents.
What should I write if a measurement changes across the item?
Name the section measured or give separate labeled measurements for the varying parts. Avoid implying that one figure describes the whole item uniformly.
