Newbie question about props/static meshes and more

Yeah I have centimeters when I export but it still doesn’t appear to match :/, even when I try and do the whole grid size in Maya. What does appear to work is when I’m importing it if I change the uniform import scale anywhere from 30-50 (from 1 originally) then I start to get the size that I’d imagined something to be. If I use the uniform import scale will it affect textures and materials on the object? I google’d a bit and saw some people had some size problems and regular scaling would cause their textures to be extremely stretched and low quality.
