How to Check Tape Measure Accuracy | Just Follow 4 Steps

How to Check Tape Measure Accuracy

Accuracy is key when it comes to woodworking. Every woodworker uses a tape measure to obtain measurements for their project. 

Your tap measure should be accurate. The accuracy of a tape measure can make or break your project. Even small inaccuracies can result in cutting too short, which means you’re going to have to sand and re-cut everything. 

It’s not just time-consuming, it also makes the job more difficult because the wood is harder to work with after being cut once. 

Before you use your measuring tape, you must check its accuracy. We will discuss how to check tape measure accuracy to ensure that your project turns out perfectly.

Why Calibrate a Tape Measure?

How to Check Tape Measure Accuracy? Step-By-Step Guide

It is clear why you should calibrate your measuring tape before each use. Now that we’ve gone over the reasons let’s discuss the way to check the measuring tape’s accuracy. By following these steps, you can be sure that your measuring tape is giving you accurate measurements:

Step 01: Take a Tape Measure Calibration Tool

The first step is to take a tape measure calibrator. This is the main tool you will use to check the accuracy of your measuring tape. A tape measure calibrator is a small, handheld tool that is used to measure the accuracy of tape measures.

There are many different types and brands of measuring tape calibrators on the market. It is important to choose the best tape measure calibration tool that is designed for checking the accuracy of tape measures. 

On the end of a measuring tape calibrating device, there is a small cutout that is used to hold the tape measure. Additionally, there is a graduation mark on the side of the calibrator. This mark is used to determine the accuracy of the measuring tape.

Step 02: Place the Calibrator on a Smooth surface

Next, you will need to place the calibrator on a smooth surface. You want to make sure that the surface is level and free of any bumps or imperfections. This will ensure that the calibrator is able to accurately measure the tape measure.

Step 03: Insert the Tape Measure into the Calibrator

Once the calibrator is in place, you will need to insert the measuring tape into the hook tab cutout on the end of the tape measure calibration tool. Make sure that the tape measure is inserted all the way into the calibrator.

Step 04: Check the Graduation Mark

Once the tape measure is inserted in the correct position, pull the measuring tape out of the calibrator. You can check the pull measurement and push measurement. Check the calibration marks on the side of the calibrating devices. 

This mark will indicate the accuracy of the measuring tape. If the graduation mark number and the tape measure line number match, then the tape measure is accurate. However, if both the push and pull measurements numbers do not match, then the measuring tape is not accurate.

By following these steps, you can check the accuracy of your measuring tape. By ensuring that your tape measure is accurate, you can improve your woodworking skills and produce better results.

Why is the Tape Measure Inaccurate?

An incorrect tape measure can be frustrating and cause you to make mistakes. If you’re wondering why your measuring tape is incorrect, there are a few possible reasons:

1. Inaccurate Markings

One reason why a tape measure may be incorrect is due to inaccurate markings. When printing the tape measure, the manufacturer may use an incorrect printing plate. 

This can cause the markings on the measuring tape to be incorrect. Additionally, the tape measure may be stretched during the printing process, which can also cause the markings to be inaccurate.

2. Worn Out Tape

Another reason why a tape measure may be inaccurate is due to a worn-out tape. Over time, the tape on a tape measure can become stretched and worn out. 

This can cause the tape measure to be incorrect. Additionally, the tape may become brittle and break, which can also cause the measuring tape to be inaccurate.

3. Long Period of Use

A tape measure that has been used for a long period of time may also be inaccurate. Over time, the tape measure can become stretched and worn out. Additionally, the markings on the tape measure can fade, making it difficult to read.

4. Expansion or Stretching

It is also possible for a measuring tape to become inexact due to expansion or stretching. This can happen if the tape measure is exposed to extreme heat or cold. Additionally, the tape measure may be stretched if it is pulled too tight.

5. Damage

Finally, a tape measure can become inaccurate if it is damaged. The tape may become frayed or broken, which can cause the tape measure to be incorrect. 

Additionally, the housing of the tape measure may become bent or damaged, which can also cause the tape measure to be incorrect.

Checking the measurement accuracy is an important step in ensuring that your woodworking projects are successful. By taking the time to check your tape measure, you can avoid making mistakes and produce better results.

Frequently Asked Questions:

There are a few frequently asked questions when it comes to tape measures. Here are a few of the most common questions and their answers:
