Blizzard has outlined the new Battleground brackets in a blog entry on the official site, and they span five levels each except for the final bracket for level 85 players. Blizzard believes these brackets will match up teams more evenly and "should offer players a more consistently competitive experience in the Battlegrounds as their characters level." Here are the new brackets:

10-14               30-34               50-54               70-74
15-19               35-39               55-59               75-79
20-24               40-44               60-64               80-84
25-29               45-49               65-69               85

Players will also be able to enter Arathi Basin at level 10, Eye of the Storm at level 35 and Alterac Valley at level 45. Will you be queuing for Battlegrounds as you level a new character in Cataclysm?
