Hey there! As a supplier of plastic storage cabinets, I often get asked about how to measure the internal space of these cabinets. It's a crucial step, whether you're looking to organize your home, office, or warehouse. In this blog, I'll walk you through the process step by step.

Why Measuring Matters

First off, why bother measuring the internal space of a plastic storage cabinet? Well, it helps you figure out what can actually fit inside. You don't want to buy a cabinet only to find out that your large items won't fit, or that you're not using the space efficiently. By measuring, you can make informed decisions about which Rotating Storage Cabinet or Round Cabinets 2 Level is right for your needs.

Tools You'll Need

Before you start measuring, gather a few essential tools. You'll need a tape measure, of course. A good quality one with both metric and imperial units is ideal. You might also want a notepad and a pen to jot down your measurements. If you're tech-savvy, you could use a measuring app on your phone, but I still prefer the old-fashioned tape measure for accuracy.

Step 1: Empty the Cabinet

If your cabinet is already filled with stuff, you'll need to empty it out. This gives you a clear view of the entire internal space and makes it easier to measure. Take this opportunity to declutter and decide what you really want to keep in the cabinet.

Step 2: Measure the Height

Start by measuring the height of the cabinet. Place the end of the tape measure at the bottom of the cabinet and extend it straight up to the top. Make sure the tape measure is flush against the back of the cabinet for an accurate measurement. Write down the height measurement. Keep in mind that if your cabinet has shelves, you may want to measure the height between each shelf separately, especially if you plan to store tall items.

Step 3: Measure the Width

Next, measure the width of the cabinet. Place the tape measure across the front of the cabinet, from one side to the other. Again, ensure the tape measure is straight and level. Write down the width measurement. If your cabinet has a curved front or a non-uniform shape, you may need to take multiple width measurements at different points and note the widest and narrowest parts.

Step 4: Measure the Depth

Now, measure the depth of the cabinet. Insert the tape measure from the front of the cabinet to the back. Measure at the center of the cabinet and at the sides to account for any irregularities. Write down the depth measurement. Some cabinets may have a deeper section at the back or a sloped interior, so it's important to measure carefully.

Step 5: Calculate the Volume

Once you have the height, width, and depth measurements, you can calculate the volume of the cabinet. The formula for volume is height x width x depth. For example, if your cabinet has a height of 36 inches, a width of 24 inches, and a depth of 18 inches, the volume would be 36 x 24 x 18 = 15,552 cubic inches. If you prefer to use metric units, convert your measurements to centimeters first and then calculate the volume in cubic centimeters.

Step 6: Account for Obstructions

Don't forget to account for any obstructions inside the cabinet, such as shelves, dividers, or hinges. These can reduce the usable space. Measure the thickness of the shelves and subtract this from the height measurement if you're calculating the space between shelves. If there are dividers, measure their width and subtract this from the width measurement.

Step 7: Consider the Shape

Not all plastic storage cabinets are rectangular. Some may be Round Cabinets 2 Level or have other unique shapes. For round cabinets, you'll need to measure the diameter and the height. The formula for the volume of a cylinder (which is a good approximation for a round cabinet) is π x (radius squared) x height. The radius is half of the diameter.

Step 8: Evaluate Your Needs

Now that you have the measurements, it's time to evaluate your needs. Think about what you want to store in the cabinet. If you're storing large items like suitcases or camping gear, you'll need a cabinet with a large volume and few obstructions. If you're storing small items like office supplies or craft materials, you may be able to use a cabinet with more shelves and dividers.
