How to Measure the Terrace ? Easy Method

Calculate the Area of a Terrace

Step 1: Measure the Terrace Length and Width

Most terraces are rectangular or square in shape. Use a steel tape or laser measure to note down the length and width in feet.

Example:

  • Length = 50 feet

  • Width = 25 feet

Step 2: Apply the Basic Formula

The formula for terrace area is simple:

Area (sq ft) = Length × Width

Example Calculation:
50 ft × 25 ft = 1,250 square feet

Step 3: Subtract Obstructions

Many terraces include features like water tanks, staircases, or solar panels. Measure the footprint of these obstructions and subtract them from the total area.

Example:

  • Staircase area = 80 sq ft

  • Tank base area = 20 sq ft

  • Net Terrace Area = 1,250 – (80 + 20) = 1,150 square feet

Step 4: Add a Safety Margin

For waterproofing, always include an extra 5–10% to cover joints, edges, and overlaps. This ensures complete coverage and prevents leaks.

Why Accurate Calculation is Important

  • Cost Efficiency – Prevents over-purchasing or under-purchasing waterproofing materials.

  • Better Planning – Helps contractors estimate labor and project time.

  • Long-lasting Results – Proper material coverage means stronger, leak-proof protection.
