Easton leaves some height and weight combinations blank. The finder then uses the nearest charted size in the same weight row.

How to find the right bat, in 3 steps

Measure height and weight
Use current numbers, since kids change fast. Enter height in inches (4 ft 3 in is 51).
Read the finder and the chart
Find your weight row and height column in the chart. Add an age to compare with the makers' age tables, and note any gap.
Check the rules, then try a bat
Match the bat mark and length limit to your league. Then try nearby lengths before you buy, as Louisville Slugger suggests.

Frequently asked questions

What size baseball bat does my child need?

Makers start from height and weight and then check age. Easton and Louisville Slugger both list 26 to 28 inches for ages 8 to 9 and 30 to 31 inches for ages 11 to 12. Use the finder, then try a few bats.

What does "drop" mean on a bat?

Drop is the bat's length in inches minus its weight in ounces. Rawlings' example: a 30-inch, -10 bat weighs 20 ounces. A lower drop number is heavier and tends to be more powerful, but a bat that is too heavy slows the swing.

Which drop should I pick?

Rawlings says there is no right drop for an age: it depends on skill and strength, and players under 11 generally use a -10 or higher drop number (a lighter bat) while older players can move to -8 or -5. Louisville Slugger lists age bands in the table above.

USABat, USSSA or BBCOR: which one?

Ask your league. Little League requires the USABat mark in Minors and Majors, allows USABat or BBCOR in Intermediate (50/70) and Junior, and requires BBCOR in Senior. USSSA bats are made for travel ball.

How long can a Little League bat be?

Minors and Majors: no more than 33 inches. Intermediate (50/70) and Junior: 34 inches. Senior: 36 inches. The barrel is capped at 2 5/8 inches in all of them.

What size is a tee ball bat?

Rawlings points tee ball players to 24 to 26 inches, and Little League's certified Tee Ball bats are 26 inches and shorter, marked for use with approved tee balls.

Is a longer bat better?

Not always. Louisville Slugger notes that many players assume a longer bat means more plate coverage, but a bat that is too long can slow the swing and one that is too short limits coverage.

My height and weight point to different sizes. What now?

That happens because makers' charts differ. The finder shows the span between them. Louisville Slugger's advice is to demo bats when you can.
