If you're getting into model railroading, the first real decision you'll make is which scale to build in. For most people in North America, that comes down to two choices: HO scale vs N scale. Pick the right one and the hobby feels effortless. Pick the wrong one for your space or budget and you'll feel it every time you reach for the track. This guide breaks down the difference so you can choose with confidence.
What "scale" actually means
A scale is simply the ratio between the model and the real thing. HO scale is 1:87 — the model is 1/87th the size of the prototype. N scale is 1:160, roughly half the size of HO. That single difference ripples through everything else: how much detail you can see, how much track you can fit, and how much it all costs.
HO scale: the popular all-rounder
HO is the most widely modeled scale in Canada and the United States, and that popularity is its biggest advantage. Because so many people build in HO, manufacturers make more of everything — locomotives, freight cars, buildings, figures, and parts.
What HO does well:
- Detail and handling. At 1:87 the models are big enough to show fine detail and easy to pick up, couple, and put on the track — a real plus if your hands aren't as steady as they used to be.
- The widest selection. If you want a specific railroad, era, or car type, you're most likely to find it in HO.
- Forgiving for projects. Weathering, adding lights, and kitbashing are all easier when the parts are larger.
The trade-off: HO takes more room. A simple oval lives happily on a 4×8-foot sheet of plywood, but a sprawling layout needs real space.

N scale: big railroading in a small footprint
N scale (1:160) is about half the size of HO, and that's exactly the point. With N scale you can run long, realistic trains through tall scenery on a layout that fits where HO never could.
What N scale does well:
- Space efficiency. A satisfying N scale layout fits on a 2×4-foot board — ideal for apartments, condos, or a shelf.
- Longer trains, bigger scenes. Because everything is smaller, you can model sweeping curves, full-length trains, and more landscape in the same area.
- Often a lower entry cost. Starter sets and individual cars tend to be a little easier on the wallet.
The trade-off: the small size means finer detail work is fiddlier, and the selection — while excellent — isn't quite as deep as HO.

HO vs N scale at a glance
| HO scale (1:87) | N scale (1:160) | |
|---|---|---|
| Relative size | Larger, easier to handle | About half of HO |
| Space needed | More (4×8 ft for a basic loop) | Less (fits 2×4 ft) |
| Detail | Easier to see and add | Finer, more delicate |
| Selection | Widest available | Excellent, slightly narrower |
| Best for | Detail lovers, first-timers, those with space | Small spaces, long trains, big scenery |
So which should you choose?
Ask yourself three questions:
- How much space do I realistically have? Tight on room? N scale. Have a spare table or basement corner? HO opens up.
- Do I want to see and add fine detail, or run long trains through big scenery? Detail and easy handling lean HO; scope and scenery lean N.
- What feels right in my hands? If you can, handle both in person before deciding.
There's no wrong answer — both are mature, well-supported scales with decades of products behind them. Many modelers even run both over time.
A note on freight cars
Whichever scale you land on, freight cars are where a lot of the fun (and collecting) lives. We carry a deep selection of rolling stock — including 100-ton hoppers in authentic railroad paint schemes — in both scales. Have a look at the rolling stock collection once you've picked your scale.
Frequently asked questions
Is HO or N scale better for beginners? HO is the common recommendation for first-timers because the larger size is easier to handle and the selection is the widest. That said, if space is your main constraint, N scale is a perfectly good place to start.
Is N scale more expensive than HO? Often N scale cars and sets cost a little less, but prices vary by manufacturer and how detailed the model is. The bigger cost driver is usually how much you buy, not the scale itself.
Can I mix HO and N scale on one layout? No — they're different sizes and run on different track. Pick one scale per layout. Many hobbyists do keep separate layouts in each scale, though.
How much space do I need to start? A basic HO loop fits on a 4×8-foot board; a basic N scale loop fits on roughly 2×4 feet. You can start even smaller with a shelf switching layout in either scale.
