Texas King vs California King: The Long-Format Custom Mattress Compared
Texas King is 80 by 98 inches: 14 inches longer than Cal King and 8 inches wider. It is the custom format designed for the extreme-tall sleeper. This page covers when Texas makes sense over Cal King.
Last verified April 2026
Texas King is one of the custom oversize king formats, sized at 80 by 98 inches. Its defining feature is length: at 98 inches (8 feet 2 inches), it is the longest commonly-marketed custom mattress short of the square Alaskan King. The 14-inch length premium over Cal King is the reason to buy Texas King.
This page is for the genuinely extreme-tall sleeper or for households where stretching length is the binding constraint, not shared width. Most King-class buyers should not consider Texas King; Cal King's 84-inch length handles up to about 6 feet 8 inches of sleeper height comfortably.
The size comparison
| Size | Dimensions (in) | Dimensions (ft) | Square feet | Sleeper height clearance |
|---|---|---|---|---|
| California King | 72 x 84 | 6 x 7 | 42.0 | Up to 6 ft 6 in comfortable |
| Texas King | 80 x 98 | 6 ft 8 in x 8 ft 2 in | 54.4 | Up to 7 ft 6 in comfortable |
| Difference | +8 in W, +14 in L | +8 in W, +14 in L | +12.4 sq ft | +1 ft of accommodated height |
Cal King dimensions from the ISPA size schedule[1]. Texas King is a non-ISPA custom size; specification varies slightly by manufacturer (some Texas Kings are 80 by 98, others 80 by 100). The 80 by 98 is the most common.
When Texas King is the right call
The genuinely-justifying cases for Texas King over Cal King:
- Sleeper over 7 feet tall: An NBA-frame buyer (7 ft to 7 ft 6 in) on Cal King has 0 to 12 inches of clearance, which combined with a 2-to-4 inch footboard means feet at or off the foot of the bed. Texas King provides 22 to 26 inches of clearance for the same sleeper.
- Two tall sleepers: A couple where both are 6 ft 4 in or taller benefits from the 14 inches of extra length on Texas King, especially if both stomach-sleep or back-sleep stretched.
- Tandem-stretch sleep: Rare layout where two sleepers occupy the bed head-to-foot instead of side-by-side. Texas King's 98-inch length accommodates two adults stretched in this orientation; Cal King's 84 inches does not.
- Pillow-stack-plus-tall-sleeper: A 6 ft 6 in sleeper plus a partner who stacks 8 inches of reading pillows on Cal King has zero effective clearance. Texas King restores 14 inches of buffer.
When Cal King is still the right call
Stay with Cal King in essentially all standard cases:
- Tallest sleeper in household is under 6 ft 6 in
- Bedroom is under 13 by 13 feet (Texas King's 98-inch length needs significant floor space)
- Budget is under $4,000 (Texas King all-in starts above this)
- You expect to move within 5 years (specialty-format mattresses are hard to relocate)
- You value width over length (Texas King adds only 8 inches of width vs Cal King)
Bedroom-fit reality
A Texas King mattress occupies a 98-inch (8 ft 2 in) long footprint. Adding 24-inch nightstand clearance at the head and 24-inch foot-of-bed walkway clearance brings the required wall-to-wall length to 146 inches (12 ft 2 in). Most US residential bedrooms have a longer dimension of 12 to 16 feet, so Texas King requires the bedroom be oriented with the longer wall accommodating the mattress length.
Width is less constrained: the 80-inch width plus 30-inch walkway clearance per side requires 140 inches (11 ft 8 in). This is workable in a 12 by 14 foot bedroom. Tighter than Standard King because of the length, not the width.
The all-in cost expectation
| Item | Typical Texas King cost |
|---|---|
| Mattress (mid-tier construction) | $3,000 to $5,500 |
| Bed frame (platform, basic) | $1,200 to $2,800 |
| Sheet set (one set) | $350 to $800 |
| Mattress protector | $180 to $400 |
| Comforter or duvet | $350 to $1,000 |
| Pillows (uses standard pillows) | $60 to $300 |
| Total first-year all-in | $5,140 to $10,800 |

The honest recommendation
Texas King is a single-purpose mattress: extreme length for extreme-tall sleepers. If you are 7 feet or taller, or your partner is, Texas King is the practical answer. Cal King at 84 inches works to about 6 ft 8 in comfortably; above that, length becomes a binding constraint that only Texas King or Alaskan King solves.
For two-sleeper households where both are under 6 ft 6 in, Cal King is sufficient and Texas King is over-spec. For households needing more width than length, Wyoming King (84 by 84) is the better step up. See Wyoming King vs Cal King and Alaskan King vs Cal King for the alternative oversize formats.
