Don’t Stop at Construction Cost—Other Useful Calculations

Knowing your total cost is great, but understanding how to measure square footage for various purposes can also help in tasks like flooring, paint buying, and space planning.

How to Calculate Square Feet of a Room

Why it matters: This is essential when planning flooring, painting, or placing furniture.

Formula:

Area (sq. ft.) = Length (ft) × Width (ft)

Example: A room measuring 10 feet by 12 feet would have an area of 120 square feet.

???? Suggestion: When calculating the entire home, sum up the square footage of all rooms, hallways, and even balconies.

How to Convert CM to Square Feet

Why it matters: Sometimes, tile or marble sizes are given in centimeters, especially if imported. You'll need to convert them into square feet to determine the quantity required

Formula: 

(Length × Width in cm) ÷ 929.0304 = Area in square feet

A 60 cm × 60 cm tile, for example, covers roughly 3.87 square feet.

How to Calculate Square Feet for Tiles

Why it matters: Tiles are sold per box in square feet. An incorrect calculation could lead to running out of materials or spending more than necessary.

Formula:

Room Area (in sq. ft.) ÷ Tile Area (in sq. ft.) = No. of Tiles Needed

???? Pro Tip: Always add 5–10% extra for cutting and breakage. This small buffer can save you a lot of last-minute trouble.
