Small rocks
Start With the Scale
Read the final size digit of the product number to choose a believable small rock for N, HO, O, or G scale.
Small-Rock Starting Numbers
These are the starting endings for a small-rock appearance. Move up a number when the scene needs a larger rock.
| Rock size | N scale | HO scale | O scale | G scale |
|---|---|---|---|---|
| Small rock | ends in 3 | ends in 4 | ends in 5 | ends in 6 |
Example: an item ending in 5 can be a small rock in O scale, a medium rock in HO scale, or a larger rock in N scale.
The special 03 ending
Products ending specifically in 03 are listed in Sand & Gravel. They can also be used as rip rap, particularly where a fine rip-rap appearance is needed.
