U.S. map practice index
U.S. States to draw from memory
Browse all fifty state outlines from the simplest geometry in this map source to the most detailed, then use one visual anchor to rebuild each shape without looking.
Choose a difficulty
Start with one strong border clue
Easy states use fewer coordinate vertices in the project's us-atlas source; medium and hard states use progressively more. That makes the grouping automatic and reproducible, but it is not a psychological test. A familiar shape such as Texas can still feel easier than a low-vertex state you rarely see. Use the ranking as a route through the data, then let your own repeated mistakes decide what needs practice.
Medium outlines
17 states to practice
Rank 1 has the fewest source vertices; rank 50 has the most.
- #18
Medium · 130 vertices
Nebraska
Hold the long west-east proportion and simplify the Missouri River edge.
- #19
Medium · 155 vertices
Massachusetts
Draw the mainland bar before curling Cape Cod outward.
- #20
Medium · 160 vertices
South Carolina
Think rounded triangle with the point aimed northwest.
- #21
Medium · 163 vertices
Indiana
Start with a compact upright block and notch the northwest corner.
- #22
Medium · 165 vertices
Oklahoma
The long western panhandle is the anchor for the broader eastern body.
- #23
Medium · 167 vertices
Tennessee
Preserve the very long horizontal strip before adding border wiggles.
- #24
Medium · 168 vertices
Ohio
Use a compact shield shape with a flatter west and curved river south.
- #25
Medium · 178 vertices
Iowa
Use a broad box held between two gently curving river borders.
- #26
Medium · 194 vertices
Oregon
Start boxy, then replace the western side with one Pacific coastal curve.
- #27
Medium · 196 vertices
Georgia
Use a broad upper block and taper toward the short Atlantic coast.
- #28
Medium · 199 vertices
Arkansas
Start with a compact box, then soften the east with the Mississippi River.
- #29
Medium · 204 vertices
Montana
Use a wide northern band with a rougher, narrower mountain side below.
- #30
Medium · 206 vertices
Hawaii
Place the main islands on one northwest-to-southeast diagonal.
- #31
Medium · 224 vertices
Missouri
Draw a central block, soften both river edges, and add the bootheel.
- #32
Medium · 233 vertices
West Virginia
Find the compact center first, then extend both thin panhandles.
- #33
Medium · 235 vertices
Illinois
Keep it vertical and let the Mississippi River bend the western edge.
- #34
Medium · 249 vertices
Idaho
Draw the tall northern handle first, then widen sharply across the south.
The order counts coordinate vertices after converting us-atlas/states-10m.json to GeoJSON. Dataset resolution, island inclusion, and river detail all affect the count, so “hard” here means a more detailed source path rather than a guaranteed harder memory task.
