I am also 5 feet tall and this drives me crazy too..I keep mine in exactly the same spot you do..right in the cabinet to the left of the stove..except I seem to accumulate so many that I have 2 shelves worth...I hate when I reach into the back and they all fall over, spilling stuff...one heavy fell down one and chipped my stove...so, this works for me..
I put my spices into tins..like the square cookie tins..or a square or rectangular plastic container..one whose lid broke or something and I put them in there..this way I just slide out the whole box...and if something spills it stays in there..not all over the counter..helps for my kids too because when they cook things go flying..but at least they do cook...
Best of all, it doesn't cost anything..the ones you buy..they wouldn't work for me because all my spice containers are different sizes...
