Media queries for tablet min-resolution and max-resolution

Question

Currently working on a responsive design website. I use media query for targeting different devices based on the width and screen resolution.

1. I have a scena

Answer 1

According to older measurement by Quircksmode http://quirksmode.org/tablets.html

@media screen and (min-width: 37em) {
}

however, this doesn't work best for newer tablets I guess, since my phone has 37em or more.

What about:

@media screen and (min-width: 42em) {
}
