Alice Longbottom is 5′9″ (or 1.75 meters), which puts her just a smidge taller than her mentor and co-worker, Alastor Moody—although since he wears taller boots than she does, it isn’t usually obvious—and two inches shorter than her husband, Frank.
Having grown-up around many taller people, and coming from a family that all share similar or greater heights, Alice doesn’t tend to think of herself as particularly tall, although she is a little above average. Regardless, she thinks herself a perfectly reasonable height: tall enough that she can reach most shelves with ease, but not so tall that she has to duck to go under doorways. If she were asked, Alice would say that the most tedious part of her height is the fact that most chairs seem to have been designed for shorter people, and those extra few inches can be annoying to deal with when one is sitting for any length of time—at least so long as one is expected to maintain proper posture in said too-short-legged chairs. Alice is thus prone to crossing or curling or propping her legs up on things rather than sitting in a properly demure and ladylike position. If they wanted her to be ladylike, they should have designed chairs that were comfortable.
She’s also not particularly fond of the way off-the-rack robes are all so short in the sleeves (broad shoulders compound the problem of arm length for her) but between the Longbottom fortune and the generous wages she makes as an Auror, that’s easily worked-around by simply ordering only bespoke instead.
