Spectrum #46: Order these mattress sizes by width — the solution
The Spectrum puzzle from September 29, 2026: six things on one hidden scale, narrowest to widest, with every figure and where the checks were best spent.
The puzzle
Order these mattress sizes by width, narrowest at the top and widest at the bottom. The board opened in this order:
- California King
- Twin
- King
- Full
- Crib
- Queen
Twin was already in place; California King opened 4 places from home.
The walkthrough
The ends first. Crib is the narrowest of the six at 28 in and King the widest at 76 in. Anchor those and the middle four are what is left to place.
Where the scale splits. The widest gap is between Twin (38 in) and Full (54 in) — 16 in apart. Everything above that line belongs on the narrowest side and everything below it on the widest side, so sorting the six into those two groups is most of the puzzle.
The closest call. California King (72 in) and King (76 in) are only 4 in apart — the pair that is a coin flip without the figures, and the place to spend a check: a check locks whatever is already right and leaves only the wrong tiles to swap.
The answer
| # | Narrowest to Widest | Figure |
|---|---|---|
| 1 | Crib | 28 in |
| 2 | Twin | 38 in |
| 3 | Full | 54 in |
| 4 | Queen | 60 in |
| 5 | California King | 72 in |
| 6 | King | 76 in |
