How To Weigh Yourself Without A Scale In Two Simple Ways And A Bonus Method You Need To Know!

Are you wondering what your weight is but you do not have a weighing scale on hand? There are times when this happens to us, and oftentimes, we just let go of the idea of determining our weight because after all, we have no weighing scale, it is impossible to do that, right?

Before you totally give up on the idea of determining your weight without a scale, let me tell you that there are actually two ways on how to weigh yourself without scale. Yes, it may not be as convenient as just simply stepping on a weighing scale, but these two methods do work!

So are you excited to find out how you can do this seemingly impossible feat? If so, continue reading!

The Steps On How To Weigh Yourself Without Scale

How To Weigh Yourself Without A Scale

As mentioned above, there are two ways on how you can get your weight without weighing scale. Here they are:


Method #1: Archimedes Principle

Sorry, guys if I decided to dive straight in the scientific way. If science is not your favorite subject, then you may be checking out of this article as early as now, but I promise you, this method is a fun and enjoyable one so please stay tuned to this article.

Maybe you are already familiar with the Archimedes principle. If you aren’t, this principle states that since our body is 70% water, it is most likely that our bodies have the same density as water. Density is calculated as weight over unit volume of an item.

In the case of water, it is a gram for one cubic centimeter. With this in mind, we can determine your weight through the volume of water that will be displaced.

  • Step 1: Find a container that is big enough for you to submerge yourself in and measure its top surface area.

Measure the length and width of the container and get its surface area by multiplying the length with the width. Using a marker or grease pencil, leave a mark the height that is slightly below the top of the container.

Pro Tip: A bath tub is one of the best containers that you can use.

  • Step 2: Fill the container.

Fill the container with water until it reaches the height that you have marked earlier.

  • Step 3: Submerge yourself in the tub.

Now get into the tub or whatever container you have decided to use. Make sure that nothing will come over the surface. While you are submerged in the container, mark the level of water inside the container.

Pro Tip: It is best that you get a friend to help you out with this.

  • Step 4: Measure the distance.

Measure the distance (vertically) between the two marks that you have left behind. Make sure to use centimeters in measuring the distance for easy computation.

  • Step 5: Determine the volume of water that has been displaced by your body.

The formula for volume is area of the container x distance displaced. So, for example, if the area of your container is 15 cm x 20 cm and the distance is 10 cm, then the formula would be volume= 15 x 20 x 10 so the answer is 3,000 cubic centimeters.

  • Step 6: Using the density formula, get the weight.

As mentioned above, density is weight over unit volume of the item. Deriving the weight from this formula, if the volume is 3000 cubic centimeters, then it would equal to 3000 g or 3 kilograms. Whatever kilogram you will get, that is your weight.


Method #2: Fulcrum And Lever Method

This is another effective (and a much convenient one, at that) method in measuring yourself without a weighing scale. For this method, you will use the number of cans as basis in getting your weight. Here are the steps you need to take on how to do this:

  • Step 1: Balance the see-saw.

Sit at one of the ends of the see-saw. While you are sitting at the end, ask a friend to place a 1-gallon can containing either water or paint at the other end. Continue adding paint cans until the ends of the see-saw are already perfectly balanced.

Pro Tip: You can try adding smaller loads like half gallon cans or quarter gallon cans so you can achieve the perfect balance.

  • Step 2: Now, get your estimated weight.

To get your weight (in pounds), get the number of cans that were used and multiply the amount by 8.33 (considering that you have used only one-gallon cans). If you have used 10 one-gallon cans, it would be 10 x 8.33 and your weight would be, 83.3 pounds. 

In the event that you have used a half-gallon or a quarter-gallon can, you should count the cans separately. For example, if you have used 10 1-gallon, 1 half-gallon and 1 quarter gallon cans, the computation will go like this: 10 + 0.5 + 0.25= 10.75 cans. To get your weight, multiply this with 8.33 so the answer would be 89.55. This means you weigh 89.55 pounds.


Bonus Method: Body Fat Measurement

This method will not help you to determine your current weight but it can help you determine how much weight you have lost (and sometimes, that is more important!).

  • Step 1: Measure your body fat.

A body fat scale would be suitable for this but if you have none, you can measure your body fat by using a skin fold caliper. Measure the thigh, triceps and suprailiac. Here is a simple video that will show you how to do the measurement:

  • Step 2: Get the circumference of your waist.

How big your waist is will help you determine the amount of visceral fat that your body has.Measure your weight by using a soft tape measure and loop it around the waist. Keep your abdomen relaxed as you do this. Just like the caliper method, you should do this once a month.

In the event that the waist circumference and the body fat measurement is getting lower each and every month, it means that you are losing weight. You can continue doing what you are doing because you are doing things right!


If you do not have a weighing scale, it may seem like it is impossible for you to determine your weight. Well, it is possible! In fact, we have two methods on how you can determine your weight without scale and while these two methods are a bit complicated, it can be done.

In addition to that, I have also provided you with two bonus methods on how you can determine weight loss without weighing scale. This will definitely come handy for people who do not have a weighing scale but would want to track their progress and monitor their weight.
