Canada chart
Key:
| 1 - heavy clay | 6 - loamy sand | 11 - silty clay loam |
| 2 - clay | 7 - sand | 12 - silt loam |
| 3 - sandy clay | 8 - clay loam | 13 - silt |
| 4 - sandy clay loam | 9 - loam | |
| 5 - sandy loam | 10 - silty clay |
Note: The official Canadian soil chart is actually a biaxial chart with %clay and %sand as the axes. However, I have converted their offical chart into a triaxial chart as shown above so you can see the values for %silt as well.
Sizes of primary particles:
| Clay (mm) | Sand (mm) | Silt (mm) |
| <0.002 | 0.05 - 2.0 | 0.002 - 0.05 |
