layout compatibility is very important part of any project

sorry but you have to use dimens for handle this problem. and i think best way for design is use density.

you can use dimens-hdpi or dimens-mdpi or ...

and can use dimens-small or dimens-large or ...

and can use both of them together. like dimens-larg-mdpi

but this is so hard to design.

i using dimens smallest screen width this use density and i think you can handle all of phones or tablets by 4 or 5 dimens.

like this picture.

Typical numbers for screen width dp are:

320: a phone screen (240x320 ldpi, 320x480 mdpi, 480x800 hdpi, etc).
480: a tweener tablet like the Streak (480x800 mdpi).
600: a 7” tablet (600x1024).
720: a 10” tablet (720x1280, 800x1280, etc).
if you have a device don't support by one of these you can add another smallest screen width for that.

you can read more details here , here , here and this help you know your phone pixels per inch.

example:

you have a phone 1080*1920 pixel and 5" size.

this phone have 392 dp in width and smallest width for that is 320.

if you like use dpi Pixel ratio can help you.
