Map types and sources
A useful map begins with the question you are asking. An outline shows shape; a county map adds local divisions; a road or topographic map answers different questions.
State outline maps
An outline map traces the outside boundary of one state without internal labels or divisions. It works well for a worksheet, a broad geographic comparison, or an illustration where other information will be added later. Our outline SVGs use the 2025 U.S. Census Bureau cartographic boundary for each state. Alaska and Hawaii are separate maps, so their shapes can be viewed at a useful size without relying on a national inset.
County and equivalent maps
A county map adds the boundaries of counties or their equivalents inside the state. The Census Bureau’s national county files include Louisiana’s parishes, Alaska’s boroughs and census areas, and Washington, D.C., as a county equivalent. Our county SVGs use the matching 2025 file. They show the divisions as lines; hover over a shape on a state page to see its name. Names are not printed inside the shapes, and each state page has an alphabetical list. For a precise local boundary, use a detailed Census or state GIS resource rather than reading detail into a small shape.
Road maps
Road maps focus on transportation: highways, local roads, interchanges, and destinations. Our maps contain none of that information. Routes can change, and a static boundary outline cannot tell you whether a road is open or suitable for travel. For trip planning, choose an up-to-date road map or navigation source with the detail your journey needs.
Topographic maps
Topographic maps depict the physical landscape. Depending on the product, they may include elevation contours, water features, roads, and named places. The USGS National Map provides a way to find and download U.S. topographic maps and base geographic data. Use it when relief, waterways, or terrain are more important than a simple state outline.
Scale and boundary detail
Our source is the Census Bureau’s 2025 Cartographic Boundary Files at 1:5,000,000 scale. “Cartographic” means the shapes are generalized for display. Curves, coastlines, and small islands can appear simpler than in a large-scale local dataset. A map made at this scale is useful for seeing the broad form of a state and its divisions; it is not the right source for measuring property, verifying an address, drawing a voting precinct, or making a legal determination.
The maps are available as SVG files, a vector format that can be enlarged without pixelation, and PNG files, fixed-size raster copies for common document tools. Each state page offers two boundary versions in both formats and credits the source. When sharing a map, keep the year and source with it. Boundaries and administrative units can change, so the 2025 vintage matters when you compare these images with a newer dataset.
Why the same state can look different on two maps
A map’s projection turns positions on the curved Earth into positions on a flat page. A small-scale overview also simplifies fine details so the whole country can fit. On this site, each state download is fitted to its own frame; Alaska and Hawaii are shown as separate insets on the national overview. That makes each outline easier to read, but the pictures alone do not establish a common size comparison. Use the source’s area attributes on the state pages when a land or water comparison matters.
When to use the original geographic file
If you need to combine boundaries with other geographic layers, measure an area, or label every county automatically, start with the Census Bureau’s original geographic files rather than the finished SVG. The published KML and shapefile formats preserve identifiers and attributes for geographic software. Our downloadable maps are presentation drawings made from those files. They are simpler to print, but they are not a substitute for the source records in a GIS workflow.
For a classroom handout or ordinary document, choose a state page and follow the printing guide. For a topographic product with elevation and physical features, use the USGS National Map. For a current route, use a road or navigation map that includes the roads and updates you need.
