Looking for new monitors

[claptonman]

I have my 2560x1440 monitor. I want to get two more monitors at 1440x900 and put them vertically and have them by my monitor and be equal size and resolution. The aspect ratio is 16:10.
For reference, my roommate has a 24" monitor at 16:10 ratio. The length is 20 3/8" and the height is 12 3/4".

My 2560x1440 monitor's height is 13 3/8".

What size monitor do I need?

you'll need a monitor that has the same length as your current monitor's height.
so its screen size would be 14-16", which hard to find at 1440x900.
