# D/T

Every geocache has a rating of **difficulty** and **terrain**, this is commonly shorted to **D/T** or **D/T-rating**. The difficulty and terrain is rated on a scale between 1 and 5 with the possibility of halves, for example the most common D/T-rating of all caches is 1.5/1.5. More information can be found in Geocaching.com's Help Center.

## D/T in statistics

The different D/T-ratings can be sorted in a 9x9 grid, commonly referred to as a D/T grid, "D/T matrix" or "Fizzy grid". These can be found in many places across Project-GC, for more information see D/T grid.
