Tape-measure mistakes lead to wasted time, material loss, and frustration. Get more accurate measurements by correcting these seven easy-to-fix mistakes.
Common Mistakes When Using a Tape Measure
1. Bending the Tape for Inside-to-Inside Measurements
Inside-to-inside measurements, such as measuring the inside of a window frame, are challenging to take. Bending the tape measure might seem like the right thing to do, but will lead to inaccuracies if you don’t account for the bends.
To resolve this, add the tape measure’s base width to your measurement. The base width is often printed on the tape measure, three inches being the most common.
2. Inconsistent Pressure
The amount of pressure you apply when extending the tape measure impacts the accuracy of your reading. Too much pressure causes the tape measure to bend, resulting in slight mismeasurements.
Not enough pressure causes the tape measure to slack, which can also give incorrect measurements. Fix this mistake by maintaining a consistent, gentle tension when extending the tape measure.
3. Snapping the Tape Back
It’s common to slam the tape back into the housing after taking the measurements, but doing so can damage the metal tab, shifting it out of place. After you’re done taking measurements, slowly allow the tape to retract to prevent tab damage.
4. Wrong Endpoint
One of the parts of a tape measure is the hook. It’s a metal tab at the beginning that aligns with your subject’s edge.
Failing to hold the tape measure hook against the object can lead to skewed measurements. Avoid this error by properly positioning the hook against the edge of what you’re measuring and holding the tape measure straight to obtain an accurate reading.
An alternative is skipping the hook and using the one-inch mark as the “0” point instead. If you do this, don’t forget to add one inch when processing the final measurement.
5. Poor Alignment
You’ll get inaccurate readings if your tape measure is tilted or not perpendicular to the surface. It’s crucial to ensure proper alignment of the tape measure with the surface you’re measuring.
6. Not Using a Stable Base
When measuring longer distances, have a stable base or support for the measuring tape. Holding the tape mid-air or relying on someone creates room for errors. Consider using a sturdy object or a measuring partner to ensure stability.
7. Overlooking Parallax Error
Parallax error occurs when you’re not viewing the tape measure straight on. Hence the measurement is different due to the angle of your line of sight. Make sure you’re looking at the measurement markings to avoid this mistake.
Tips and Tricks for Avoiding Mistakes When Using a Tape Measure
Use the Letter V to Mark Your Measurements
Avoid using a line, letter X, or other symbols for marking out your measurements. Use a V for the best visibility and accuracy. The exact measurement is the point where the two lines meet.
Always Measure Twice
Double-check your measurements before making cuts or permanent changes to your project.
Always Read from Left to Right
Reading the tape measure from left to right allows for precise readings. Reading from right to left affects the reading’s accuracy.
