Honestly, I had no idea!

2. Prepare the Tape Measure and Surface

Check that the tape is clean and working properly; Remove any dust, dirt, or sticky residue that may impede the movement of the tip or the stretching of the tape.

Ensure the surface being measured is stable and as flat as possible, as uneven or curved surfaces may require extra care to properly position the tip.

Extend the tape a few centimeters, then retract it to ensure it moves freely and does not stick or bend.

3. Measure external dimensions (press the tip)

For external measurements (e.g., the length of a board or the width of a table), hook the free end onto the edge of the object.

Press the tip firmly against the starting point so that it slides inward, squeezing out any slack and aligning the zero mark with the edge.

Extend the tape measure to the endpoint, keeping it taut and straight. Then read the measurement where the tape enters the housing, ensuring that the thickness of the hook is automatically accounted for.

4. Measure interior dimensions (extend the tip)

For interior measurements (e.g., the distance between two walls or the depth of a box), place the tip against one of the walls of the space.

Gently pull the tape so that the tip extends outward and rests completely against the surface, effectively increasing its thickness during the reading.

Extend the tape to the other side, press the tape body against the other surface, and record the measurement, adding the body length (usually marked on the side, e.g., 3 inches or 76 mm) for complete accuracy.

5. Check the tip position and strip alignment

Double-check that the tip is properly inserted or extended, depending on the type of measurement (pressed in for an external measurement, extended for an internal measurement), to avoid errors caused by incorrect clearance.
