How to Measure a Dumpster

When planning a project that involves renting a dumpster, understanding what “25-yard” or “15-yard” really means can save you time and frustration. Dumpster sizes refer to their volume in cubic yards, but it’s not always clear how those measurements translate into usable space.

This quick guide will walk you through how to measure a dumpster step by step, so you can confidently choose the right size for your needs.

Step-by-Step: How to Measure a Dumpster

Step 1: Understand What “Cubic Yards” Means

A cubic yard is a measurement of volume. Picture a cube that’s 3 feet long, 3 feet wide, and 3 feet high—that’s one cubic yard. Dumpster sizes are labeled based on their approximate volume in cubic yards, which helps estimate how much waste they can hold.

Step 2: Measure the Dumpster’s Dimensions

To calculate the volume of a dumpster, you’ll need to measure three things:

• Length (the longest side)
• Width (the shorter side)
• Height (from the bottom to the top edge)

Step 3: Use the Volume Formula

Once you have the dimensions, calculate the volume in cubic feet and then convert it to cubic yards:

1. Multiply Length × Width × Height (all in feet) to get the volume in cubic feet.
2. Divide the total by 27 (since there are 27 cubic feet in a cubic yard).

Example Calculation:

• For a dumpster that’s 14 feet long, 7.5 feet wide, and 4 feet tall:
  • 14 × 7.5 × 4 = 420 cubic feet
  • 420 ÷ 27 = approximately 15 cubic yards

Step 4: Know That Labels Are Approximate

Dumpster sizes, like “15-yard” or “25-yard,” are rounded estimates of their capacity. Factors like the shape of the dumpster or how waste is packed can affect how much it holds. When in doubt, reach out to a professional for guidance.

Step 5: Consider Your Waste

Different types of waste take up space in different ways:

• Bulky items, like furniture, fill up space quickly.
• Dense materials, like roofing shingles, may reach weight limits before filling the dumpster.

Make sure to estimate the type and volume of waste your project will generate.
