Perimeter is 90 ft, minus 9 ft for 3 openings = 81 ft net. With 10% waste: 89.1 ft. Requires 8 twelve-foot boards.
Measure the perimeter of your room (or use length × width × 2 for rectangular rooms), then subtract 3 feet for each doorway and opening. Add 10% for waste from cuts, corners, and splices. The result is your total linear feet of baseboard needed.
Standard baseboard heights range from 3" to 5.25". The most common heights are 3.5" for modern homes and 5.25" for traditional or higher-end finishes. Taller baseboards (6"+) are used in rooms with higher ceilings for proper visual proportion.
Longer boards (12 or 16 ft) create fewer joints, giving a cleaner finished look, but are harder to transport and handle. 8 ft boards are easiest to work with and transport. For rooms with long walls, 12 or 16 ft boards minimize visible joints. Mix lengths as needed.
Baseboard material costs $0.60 to $3.00+ per linear foot depending on material (MDF, pine, oak). Professional installation adds $2-$4 per linear foot. For a typical 15×12 room (about 44 net linear feet), expect $150-$350 total including materials and installation.
| Material | Cost/LF | Paintable | Stainable | Moisture-Safe |
|---|---|---|---|---|
| MDF | $0.60–$1.00 | Yes | No | No |
| Pine | $0.80–$1.50 | Yes | Yes | Fair |
| Oak | $2.00–$4.00 | Yes | Yes | Good |
| PVC | $1.50–$3.00 | Yes | No | Excellent |
Inside corners are typically coped (one piece is cut to fit the profile of the other) for a tighter, more durable joint. Outside corners are mitered at 45 degrees. Coping takes more skill but produces better results as it accommodates walls that are not perfectly square.
Add 10% waste for standard rectangular rooms. Add 15-20% for rooms with many corners, odd angles, or complex layouts. Extra waste accounts for cutting errors, corner adjustments, and future repairs. Always buy from the same batch for consistent color.
