Drop Ceiling Quantity Takeoff Calculator
Prepared By: Parag Kamlakar Pal – Owner of www.civilnotess.com
When estimating the quantity of materials needed for a drop ceiling installation, it’s essential to have an accurate takeoff. This guide provides a detailed calculation method along with a practical calculator for your convenience.
Calculation Details
Follow these steps to calculate the required quantities for your drop ceiling installation:
-
Determine the Area to Cover:
Measure the room dimensions and calculate the area.
Example:
- Length: 15 feet
- Width: 12 feet
- Area: 15 feet × 12 feet = 180 square feet
-
Calculate the Number of Ceiling Tiles:
Determine the tile size and calculate the number of tiles needed.
Example:
- Tile Size: 2 feet × 2 feet
- Tile Area: 2 feet × 2 feet = 4 square feet
- Number of Tiles: 180 square feet / 4 square feet = 45 tiles
-
Calculate the Amount of Grid System Needed:
Calculate the length of main and cross runners required based on standard grid spacing.
Example:
- Perimeter of Room: 2 × (15 feet + 12 feet) = 54 feet
- Main Runners Needed: 6 (rounded up from 5.75)
- Length of Main Runners: 6 × 12 feet = 72 feet
- Cross Runners Needed: 7
- Length of Cross Runners: 7 × 15 feet = 105 feet

const lengthOfCrossRunners = numberOfCrossRunners * length;
