Last Updated on December 30, 2022

Digital kitchen scales are a great way to accurately weigh out your ingredients. However, you may notice that your digital scale keeps changing weight when you are trying to measure out your ingredients. This can be problematic as it can cause you to add too much or too few ingredients to your recipe.

There are a few factors that can cause your scale to be reading inaccurately. Fortunately, by addressing these issues you can make sure your kitchen scale will measure your ingredients correctly. This will give you the best results in your recipes when baking.

Benefits of using a kitchen scale

With a properly working kitchen scale, you can use it to measure out your ingredients when baking. In fact, using a kitchen scale is generally the best way to measure out your ingredients, as it is more accurate than using measuring cups.

When using a kitchen scale, you can measure out the ingredients in ounces, grams, milliliters, and pounds. This allows you to easily measure out both wet and dry ingredients while you are baking. It gives you the exact measurement, unlike measuring cups which can be inaccurate.

Why Digital Scale Keeps Changing Weight

Many professional and home bakers have digital kitchen scales that they use while baking. Though most of the time they are easy to use and the most accurate, sometimes they malfunction. When the scales malfunction, you may notice that the weight keeps changing, even when you aren’t adding anything.

When your digital scale keeps changing weight, there are a few issues that can cause this to happen. After you figure out what may be causing this issue, you can fix the problem so your scale can work correctly.

Low battery

One of the most common causes of scales fluctuating weight is low battery. When a scale’s battery begins to run low, it can begin to work inaccurately and fluctuate as it does not have enough power to work right. When this begins to happen, it may be time for you to change out the batteries.

Uneven surface

When using your scale, be sure you only use it on a flat, even surface that is hard. If you try to use the scale on an even surface or a soft surface, such as a carpet, it will not work properly. To prevent this from happening, only use your kitchen scale on smooth, hard surfaces, and do not place it in the cracks of tiles.

Residue and grime build-up

Over time, residue and grime can build up on your scale. This can happen from food and grease in your kitchen that comes in contact with your scale when baking.

This grime and residue can build up, leaving to your scale give inaccurate readings. Be sure to regularly clean your scale to prevent build-up from grease and food from happening.

Water damage

Kitchen scales aren’t waterproof, so if water and moisture get in, they can cause damage. In some cases, the scale may not work at all, whereas at other times it may just cause inaccuracies while weighing your ingredients. If you ever spill any liquid on your scale, be sure to clean it up right away and make sure it is properly dried.

It isn’t properly calibrated

Sometimes, scales can become un-calibrated over time, causing them to not work correctly. You may need to regularly calibrate your scale so it can run properly.


Kitchen scales do have weight limits. If you add too much weight to your scale, it may cause it to overload and then lead to inaccuracies when weighing. Be sure to read the weight limit of your scale so you know what the limit is and try to avoid weighing things that are too heavy.

You moved it while using

Avoid moving your scale when you are in the process of measuring out your ingredients. Kitchen scales can be sensitive and moving them can mess up the reading of the ingredient you are adding.

What causes a scale to drift

It needs to be restarted

Like other technology, sometimes your scale simply needs to be restarted. In some cases, all you need to do is turn your scale off and then turn it back on again for it to work right.

Which Weighing Scale is the Most Accurate Digital or Analog?

When it comes to kitchen scales, you can get digital or analog options. While both options can work great, many people find that digital scales can be more accurate and the overall better choice. However, some people do prefer analog, with some even believing that analog is the better of the two choices. 

Using kitchen scales is recommended over using measuring cups. By measuring with a scale, you can measure out the account amount of the ingredient that you need. When using measuring cups there is more room for error, as you can accidentally overmeasure the ingredient, especially flour, if you are not careful.

Pros and Cons of Digital Scales

Analog scales are ideal because they are easy to read and give you accurate readings. You can also easily transition between different measurements such as grams, ounces, and milliliters. 

Since digital scales come with the ability to tare, you can easily measure different ingredients in bowls. They offer more precise measurements, giving you the exact weight of what you are weighing. However, digital scales can get quite expensive and they will likely need to be recalibrated from time to time. 

Pros and Cons of Analog Scales

One of the biggest pros of analog scales is they tend to be the cheaper option over digital scales. However, they typically only have numbers in increments of five, so it is harder to get a more precise reading. In addition, depending on the scale, the numbers can be hard to read. 

Unlike analog scales, you don’t have to worry about buying batteries, which is another added expense. Analog scales also tend to be harder than digital scales as well.
