Utah county geography overview

Utah has 29 counties, which places it 37th among the 50 state and District of Columbia maps in this atlas when ordered by number of county-level units. Their combined 82,595.9 square miles of land place the state 12th by mapped land area.

The average county-level area is 2,848 square miles, while the median is 2,427.6 square miles. The median is often the better description of a typical unit because one or two very large areas can pull the average upward. The five largest units together account for about 39% of the state’s mapped land area.

Alphabetical list of Utah counties

The table is alphabetical, so it works as a name and FIPS-code reference rather than an area ranking. Every identifier begins with the Utah state FIPS prefix 49. Land and water figures are rounded to one decimal place.

How to read and use this map

County lines are administrative boundaries, not postal routes. A mailing address can use a city name associated with a neighboring area, and ZIP codes can cross county lines. When you need to identify a county for an address, confirm it with an official geocoder or local government source.

For classroom or planning use, download a PDF from the controls above. Labelled exports use numbered callouts for crowded areas; numbered quiz maps match the alphabetical county list. SVG files keep the boundary lines sharp at larger paper sizes.
