Dumpster Calculators for Common Project Debris

Drywall Weight Calculator

Drywall, sheetrock, and plaster are some of the most common materials removed during home renovations, remodels, or commercial build-outs. These materials can add up fast — both in volume and in weight — so knowing how much you’re tossing helps you choose the right dumpster size for your project.

The weight of drywall depends on its thickness and moisture content, which means even small differences can change your total debris weight. Here’s a quick guide to help estimate:

  • 3/8-inch drywall (4’x8’ sheet): ~45 lbs
  • ½-inch drywall (4’x8’ sheet): ~51 lbs
  • 5/8-inch drywall (4’x8’ sheet): ~70 lbs

While exact weights can vary slightly by manufacturer or humidity, these averages are a solid starting point when estimating how much debris your project will produce.

Why This Matters

Drywall is deceptively heavy when stacked up — especially when removing full rooms, ceilings, or entire sections of wall. Understanding your drywall weight helps prevent overloading your dumpster and ensures you stay within your rental’s included tonnage.

A 20-yard dumpster from Riddle Roll Offs typically holds 4,000–6,000 lbs of debris, which equals around 70–90 sheets of standard drywall depending on thickness.

If your remodel involves multiple rooms or heavier materials like plaster, consider upgrading to a 40-yard dumpster or scheduling an extra haul to keep your project on track.

How to Use the Drywall Weight Calculator

  • Enter your square footage or number of drywall sheets.
  • Choose your sheet thickness (3/8″, ½”, or 5/8″).
  • Click “Calculate Weight.” You’ll get an estimate in both pounds and tons.
  • Use your total to choose the right dumpster size — or call our team for help.

Why Weight Estimates Matter

Even if your debris fits in the dumpster, it might still exceed the maximum weight limit — especially with dense materials like drywall or plaster. Using a calculator helps you avoid unexpected overweight fees and ensures a smooth haul-away process.
