For dynamically generated pages, it is a good practice to prioritize content in database in at least two* of the following:
✓ *full site, 12 inch
✓ extra large tablet, 10 inch (1200x800)
✓ large tablet, 7 inch (1024x600)
✓ *high resolution phone, 4 inch (960x600, 800x480)
✓ medium phone (480x320)
✓ small phone (320x240)
If the budget does not allow for it, all devices above 1024x600 should be considered as a full resolution screens.
