How To Measure Pillow Loft
A ruler and a flat board tell you more than a product photo. The loaded height is the number that predicts fit.

| Tool | Purpose | Cheap substitute |
|---|---|---|
| Ruler or caliper | Measure edge, center, and loaded height | Metal ruler and a book stack |
| Flat board | Spreads the load evenly | Cutting board |
| Ten pounds of weight | Simulates repeatable head load | Dumbbell, books, or water jugs |
| Phone camera | Side/back alignment photos | Any fixed camera position |
| Notebook | Night 1, 3, 7, 14, and 30 notes | Plain text file |
Measurement Steps

| Loaded loft | Put the board on top, add ten pounds, wait five minutes. | Compressed height and visible slant. |

FAQ
| Question | Answer |
|---|---|
| How many measurements should I take? | Use at least five readings: center, left, right, front third, and back third. |
| What weight should I use? | Ten pounds is a practical home load for comparing pillows on this site. |
| Are these lab numbers final? | The current rows are calculated scoring worksheets. They show the math path and should be replaced when retail units are measured. |
| Why link so many product pages? | A pillow claim is useful only when it points to the exact pillow page, specs, caveats, and money link. |
| Which review should I read first? | Start with the pillow that matches your sleep position and mattress firmness, then compare it against a cheaper control pillow. |
