Frame B rooms, by printed dimensions as published
| Room, as published | Dimensions | 2026 band |
|---|---|---|
| Office or bedroom | 10x10 | $1,000-$4,000 |
| Dining room | 12x12 | $1,400-$5,800 |
| Primary bedroom | 15x15 | $2,300-$9,000 |
| Living room | 16x20 | $3,200-$12,800 |
| Average room | 150 square feet | $1,500-$6,000 |
The dimension lines sit on the Frame B installed rate of $10 to $40 per square foot: a wider room prints a wider total in the same frame, and each band reads against its own printed footprint only.
Frame A rooms, by type and square footage as published
| Room type, as published | Square feet | 2026 band |
|---|---|---|
| Home office | 110 | $2,200-$3,300 |
| Bedroom | 132 | $2,640-$3,960 |
| Living room | 216 | $4,320-$6,480 |
| Dining room | 224 | $4,480-$6,720 |
The type lines sit on the Frame A rate of $20 to $30 per square foot, a different reading from Frame B kept apart line by line: a living room reads $4,320 to $6,480 here by type, and $3,200 to $12,800 there by dimension, never averaged.
Averages and extremes, read inside Frame B only
Frame B prints a national average of $3,800, a minimum of $900, and a maximum of $14,000, each a project-level line in that frame only. Frame A prints its own per-room average of $3,750 on the hub. The two averages stay apart: neither is a room-size line, and neither converts into the other frame.
Reading a room-size quote, as reported lines only
A room-size quote should name its room, its dimensions or type, and its frame on every line: a dimension line read in Frame B, or a type line read in Frame A.
- Room dimensions or room type named beside every band
- Frame named on every line, averages kept apart
