Measuring your weight can be a great approach to keep track of food consumption and overall health. One of the best bathroom scales that you can own is a digital weight machine. When we say ‘machine,’ we just mean using a simple digital weight scale.

A digital bathroom scale is simple to understand. In fact, it is much better than using tools that require more handy work. But like any other tool, a digital bathroom scale requires calibration after a few months. Without proper calibration, the scale will start showing inaccurate measurements.

So, before you get confused and start scratching your head after reading the weight scale, we would want you to take a deep breath. We have compiled a complete guide on how to calibrate digital bathroom scale with a few simple steps.

Things to Know Before Calibrating Digital Bathroom Scale

Before we jump into the steps, you need to know a few things. The first and most important thing to know is that you will need to calibrate it whenever you move the scale. If you don’t calibrate your scale after it’s been moved, you’ll notice weight fluctuations. Any digital scale that is moved has the potential to impact precision and reliability.

Another thing to remember is that moving on the scale can result in wrong readings. This is true for anything you place over the scale, even yourself. Don’t wobble around until the screen shows the reading once you step onto the scale or put something over the scale.

4 Steps to Digital Bathroom Scale Calibration

Follow these 4 steps to complete the calibration process and make your digital bathroom scale as good as new.

Step 1: Prepare for Calibration

The first step is to make sure the scale and tray have been carefully cleaned with a soft brush and soap. After that, dry the scale and place it on a level surface with no strong airflow around.

It’s always a good idea to turn on the digital weight scale and warm it up before starting any calibration process. Also, it’s crucial to use specific materials with a specific weight for the calibration work. When you’re trying for precision, having an approximation is worthless.

Step 2: Get the Scale into Calibration Mode

In this step, find the digital weight scale’s calibration button. It usually has one of the printed “Cal,” “Function,” “Mode,” or “Cal/Mode” on it. Now hold down this button until the digits on the scale change to “0,” “000,” or “Cal.” The digital weight scale will be in calibration mode after doing this. 

Step 3: Performing Calibration Test

After putting the scale into calibration mode, it is time to put an object over it. But before that, you must make sure that you know the weight of the object beforehand. Ideally, it would be best if you put an object that weighs a minimum of 30 pounds.

Put the object on the scale carefully. Make sure that the object does not move on the scale. Also, make sure that you place the object on the center of the scale. All these together will allow you to read the correct value from the digital scale.

Step 4: Complete the Calibration

This is the final step to the process. Begin this step by letting the scale take the complete measurement of the object you have put in on step 3. This means waiting a few seconds before the reading pops up on the screen. But that’s not the end of the process.

Once the reading is there, press the calibration button again to take the same measurement. Now, wait for a few seconds again. After the scale is done taking the measurement, you will notice a few words and numbers on the screen. They are: “Cal”, “0”, or “End”.

If your digital bathroom scale is fairly new, the machine will automatically reset after the calibration. But still, it might not happen for your machine. In that case, switch off the scale and wait a few minutes.  


Knowing how to calibrate a digital bathroom scale can save you a lot of money. It is quite common for a digital weight scale to malfunction after months of usage. The dirt, usage, and lifespan of the machine can cause it to wear out. In such a situation, calibrating it can solve measurement problems.

You can easily complete the process by following the 4 simple steps. If you still do not receive the correct reading, maybe it’s time to take the machine to a professional.
