The way airlines measure and advertise the distance between the rows is somewhat misleading (it's also always stated in inches). For them it's the distance from one point on a row to the identical point on the next row - for example, from a point on the back of the seat in front of you to the same point on the back of your seat upright.
This means it includes the thickness of the seat back itself, perhaps seven to 10 centimetres or more, which is uninhabitable space. So when pitch distance figures are thrown around, remember that this includes space that you won't physically be able to occupy.
There is a legitimate reason for the airlines doing this, according to Dave Hedges, from the website
http://www.uk-air.net. "Some airlines have thicker seat backs than others, and seat backs get worn and compress over time, so measuring the seat pitch distance this way is more accurate as it's from one fixed point to another."
Most airlines quote 31 to 34 inches as the standard pitch distance in their economy cabins. Asian airlines tend to be at the upper end of those figures, while the budget carriers in Europe, America and now Australia have squeezed them even more to 30 inches or less.
One of the main problems with pitch distance figures is that they can vary within the economy cabin of an aircraft, and between different aircraft of the same type within an airline's fleet.
What got me interested in this topic was an experience my husband and I endured late last year when we flew with Emirates to Dubai. We flew in both directions in an Airbus 340-500 series and had been looking forward to going with Emirates because of its good reputation across all classes, including economy, where we were seated.
But on boarding the aircraft and locating our seats, our spirits nosedived when we saw how close the rows were to each other. I whipped out a tape measure and checked the distance from the back of the seats in front of us to the front of our seat backs (not pitch distance in the correct sense, but a measurement of our usable airspace) and it appeared to be a mere 62 centimetres or 24.8 inches. On our return flight, in the same type of aircraft, the distance had grown by five centimetres. Apparently such discrepancies are widespread, but only in economy.
