Start at the zero mark on the tape
Identify the unit of measurement shown on the tape
Read the largest numbered mark first
Count the smaller marks between the numbered marks
Note whether the tape is marked in inches, centimeters, or both
For inches, read the whole inch number and then the fractional marks
For centimeters, read the whole centimeter number and then the millimeter marks
Keep the tape straight for an accurate reading
Make sure the tape is not twisted or slack
Read the mark where the object ends
Record the measurement clearly in the correct unit
