IDNKT. I'm going to take a look at that.
They are made so that the numbers on the tape are right-side up when the tape measure is being held in you left hand with the tape extending to the right.
Right-handed tape measures are made so that the numbers on the tape are right-side up when the tape measure is held in your right hand, with the tape extending to the left.
This never made any sense to me.
Right-handed people write with their right hand, and therefore hold the pencil in their right hand. Consequently they hold the tape measure in their left hand so that they can mark the measurement on the material with their right hand. This results in the numbers on the tape being upside-down.
The same is true, but the opposite, for a left-handed person using a left-handed tape measure.
Right-handed people should use left-handed tape measures, and left-handed people should use right-handed tape measures.
This would result in the numbers on the tape always being right-side up for both groups in most routine measuring circumstances.
Below is a left-handed tape measure. It is perfect for a right-handed person who holds the tape measure in their left hand, like most right-handed people do so that they can write with their right hand, and the numbers are right side up.
