Room Square Feet Formula:
| From: | To: |
Room square feet calculation determines the actual carpetable area of a room by measuring the length and width, then subtracting the area occupied by permanent fixtures. This ensures you purchase the correct amount of carpeting for your space.
The calculator uses the room square feet formula:
Where:
Explanation: This formula calculates the gross area of the room and subtracts areas that won't be carpeted, such as built-in cabinets, fireplace hearths, or other permanent fixtures.
Details: Accurate room measurements are crucial for purchasing the right amount of carpet, avoiding waste, and ensuring proper installation. Underestimating can lead to material shortages, while overestimating increases costs unnecessarily.
Tips: Measure the room's length and width in feet at the longest points. Calculate fixture areas by measuring their length and width, then multiply. For irregularly shaped rooms, break them into rectangular sections and calculate each separately.
Q1: How do I measure irregularly shaped rooms?
A: Divide the room into rectangular sections, calculate each area separately, then add them together before subtracting fixture areas.
Q2: What fixtures should I include in the calculation?
A: Include permanent fixtures like built-in cabinets, fireplace hearths, and other features that won't be carpeted. Don't include movable furniture.
Q3: Should I add extra for waste or pattern matching?
A: Yes, typically add 10-15% extra for waste, seams, and pattern matching, especially for patterned carpets.
Q4: How accurate do measurements need to be?
A: Measure to the nearest inch for best results. Small measurement errors can compound into significant material miscalculations.
Q5: Does this work for rooms with alcoves or bay windows?
A: Yes, treat alcoves and bay windows as additional rectangular areas. Add their square footage to the main room area before subtracting fixtures.
