If you are tall, then no amount of reclining is going to give you more space. The knees are too far forward to stretch your legs, _especially_ when the person in front of you reclines.
I'm unusually tall and flying has always been unpleasant no matter what. I can actually deal with the reclining because it's actually physically impossible for the person ahead of me to recline since my knees are in the way. What really gets me is the fact that the seat back only comes up to my neck and I can't sleep because my head just flops around. I've been meaning to find some security-friendly contraption that could extend the back a little bit to immobilize me a bit better.
I don't get this "inconsiderate" thing. The seats recline. They're designed to do so. They're allowed to do so. Airlines allow you to recline. Yes, if you're reclining during meal service, you're a dick. But any other time (outside takeoff and landing) is fair game.
If you're tall, pay for economy plus or premium economy. If that's not offered on your route, that sucks, but getting pissed that someone will use their allowed recline space isn't fair of you.
If you want to get mad, get mad at all passengers collectively for treating ticket cost as their only criterion when booking flights.
The back reclines. The bum and legs don't move. My knees usually only just fit. When someone reclines their seat usually presses on my knees. Those few cm matter.
Sometimes the seat design is such that my knees block the recline. If I'm unlucky it sucks.
I am 6'7". I regularly have to ask the person in front not to recline on some layouts. I get aisle/exit row seats if possible, but sometimes it's just not possible. For euro city flights there is no premium economy and the business class seats don't have more legroom either, so there's often very few options for me.
For short flights I will just tuck my legs awkwardly when necessary and have to get up to stretch regularly.
In other words, you are inconsiderate.
