Passing knowledge from one generation of groundskeepers to the next.

Like the old encyclopedias that used to sit in many homes, before the age of the internet, the Ballfield Dimensions & Reference Guide contains a wealth of information. Our experts have done the hard work of pulling all of their knowledge together in one place for you so you’re not wasting precious time seeking out the information.

It’s a lot of work, but it’s worth it. We painstakingly comb through the rule books of many governing bodies for baseball and softball to update any and all ballfield dimensions that are called out in their rules. And for those dimensions that groundskeepers have the liberty to adjust on your field, we’ve included space on the Field Dimension pages to record what you adjust those to, so you remember what you changed and how you did it.

Coupled with these dimensions, we include knowledge, tips and examples on:

  • Laying out your field
  • Field amenities such as dugout design, backstop netting
  • Soils – understanding them and how and why to test soil
  • Mound and Batter boxes for baseball and softball

The best tool in your shed.

The Ballfield Dimension Guide is with-out-a-doubt the most important tool in your tool shed that you will own. With six different contributors bringing decades of professional experience in soil, MLB groundskeeping and facility design, you have wealth of information at your fingertips.

If you don’t have the print version, don’t worry! We also have an interactive version of the Ballfield Dimension and Resource Guide on our website so that when you are stuck out on the field and need the information immediately, we have your back.
