How do I convert carpet from square feet to square yards?
Divide square feet by 9. For example, 120 sq ft ÷ 9 = 13.33 square yards. Carpet is often priced per square yard at retail stores, so this conversion is essential for comparing prices and ordering the right amount.
What type of carpet padding do I need?
For most residential applications, 6–8 pound rebond padding at 7/16″ thickness is ideal. For basements, use flat rubber or moisture-resistant padding. Never use padding thicker than 1/2″ as it reduces carpet life — the carpet flexes too much at seams and wears out faster.
How do I calculate carpet for stairs?
Measure the tread (horizontal) depth plus riser (vertical) height plus 1 inch for each step. Multiply by the stair width. A standard 13-step staircase typically needs about 21 linear feet of 27″-wide runner or full-width carpet. Add 10% for waste.
Should I seam carpet or buy a wider roll?
Minimize seams whenever possible — they're the weakest point. Use 15-foot rolls for rooms wider than 12 feet. Place seams in low-traffic areas, away from doorways and perpendicular to windows (so light doesn't highlight them). Professional seaming is recommended.
How long does carpet last?
Nylon carpet in moderate traffic lasts 12–15 years. Polyester: 5–10 years. Wool: 15–20+ years. Regular vacuuming, professional cleaning every 12–18 months, and quality padding extend carpet life significantly. High-traffic areas like hallways and stairs wear fastest.
