About this calculator
Overview
Carpeting is usually sold by the area, but it comes in rolls of fixed widths. Calculating the correct amount involves accounting for seams and waste from the roll width.
💡
Pro Tips
Add 10% for waste in simple rooms, and 15-20% for rooms with many corners or stairs.
Try to place seams away from high-traffic areas and doorways.
Consider the 'face weight' when comparing carpets - it's the weight of the fibers per unit area.

Fun Facts
"Most carpet rolls in the USA are 12 feet wide, but 13.5 and 15-foot options exist for larger rooms."
"Carpet padding not only makes the floor softer but also extends the life of the carpet by absorbing impact."
"The 'nap' of the carpet is the direction the fibers lean; all pieces must be laid with the nap in the same direction."
Formula: Sq Ft = Length × Width × (1 + Waste%)
Sq Yards = Sq Ft / 9
Linear Feet = Sq Ft / Roll Width
