The essential parts of a bat include the barrel size, taper and grip:
Barrel size includes the length of the barrel and its diameter. Generally, the longer the barrel, the larger the sweet spot. Smaller barrels, however, promote faster swing speed.
The bat taper is the diameter of the bat's handle. Standard bats are tapered at 31/32nds of an inch. Players who prefer to rotate their wrists may choose a narrower taper.
The grip is the bat's handle, covered in leather, synthetic leather or rubber. Leather and synthetic offer a tackier texture, which allows you to get a firm grip on your bat. Rubber, on the other hand, absorbs more shock from the ball.
The needs of an adult slowpitch softball player differ from that of their younger counterparts. Players older than 15 generally choose a bat that is at least 33-inches in length.
Weight and height are often better indicators of bat size. Most bats are weighed in ounces, with a length-to-weight ratio of -4 or -6. In other words, a 34-inch bat with a -6 drop weighs 28 ounces.
Think about your strength level and hitting style when selecting your slowpitch softball bat:
Larger, stronger players often choose a heavier bat—they benefit from the heft and swing power.
Smaller players with less strength should go for a lightweight bat—think graphite/titanium lined—which will help generate more speed at the plate.
