Where our numbers come from

Spec sheets, standards and seat maps, and why a number is where you start, not where you stop.

Illustration: in a car showroom, a tall woman sits in the driver’s seat measuring the headroom with a tape measure, a notebook on her knee.

Every guide on MadeTall is built on published numbers: carmaker specs, airline seat data, mattress standards, building codes. We link every one of them, so you can check our work. But a number is only useful if you know what it measures, so here’s how to read them.

Cars: one seat position

Headroom and legroom figures follow an industry standard, SAE J1100, which measures from one seat position. It doesn’t tell you how low the seat goes or how far the wheel reaches. Two cars with the same headroom can feel different, and a sunroof can take an inch or two away. Use the number to make a shortlist, then sit in the exact trim. The car finder flags trims that lose headroom.

Flights: pitch isn’t knee room

Airlines and reviewers publish seat pitch, the distance from one point on a seat to the same point on the seat in front. Pitch isn’t the same as the space your knees get, because thinner seats give back room the number doesn’t show. Pitch is still the best way to compare, which is why the airline guide uses it.

Beds: length is the only number that matters

Mattress sizes are standard, and that’s the useful part: a king is wider than a queen, but not longer. Both are 80 inches. The sleep guide lists every size, from a full to a Texas king.

Homes: codes are minimums

Building codes set the lowest a ceiling, doorway or beam can be, not what’s comfortable. A basement beam can legally come down to 6 ft 4 in (IRC R305). When we quote a code, read it as the floor, not the goal.

What we don’t do

We don’t guess, and we don’t round in anyone’s favor. When a number varies by trim, year or size, we show the range. When something has changed since a guide was written, we update the guide and the date.

If you spot a number that’s wrong or out of date, email hello@madetall.com. We’ll fix it and say so.
