What do screen resolutions mean?

Now that smartphones have evolved largely into touchscreen-centric multimedia devices, screen resolution and size have become some of the most important features. If the screen is too small or the resolution is too low, it can make the phone itself a hassle to use. Having a big screen is great, but it will look terrible if the resolution isn’t high enough.

Various resolutions have been created to help distinguish between each other, and here is a list of the most common ones you will find on Android powered devices:

QVGA (320x240) Used in small phones like the Motorola Charm

HVGA (480x320) Common in older devices like the HTC Hero

WVGA (800x480) The most common these days for phones like the Evo 4G

qHD (960x540) Used on high-end phones like the Motorola Atrix 4G

WSVGA (1024x600) Common for tablets like the OG Samsung Galaxy Tab

WXGA (1280x800) Used for the high-end tablets of today like the Motorola Xoom
