Assuming, like the rest of us, that you have a credit card, remember that they are all the same size - 54mm by 85mm.
The short dimension is the height of a 5' 10" person in Gauge 1 - that's 1/32nd scale.
The long dimension is the just about the height of that same person in 1/20.3 scale - that's Bachmann's Spectrum line of 3 foot gauge models.
Check out that height dimension on any railroad item you care to - your 'test guy' for 1/22.5 should measure around a fourth of an inch short of the longer side of your credit card.
Note that you can also buy a 1/24th scale 'person' at any dolls house modelling store, and use that as a quick 'feasibility check' on any new purchase. If the figure looks like Tom Cruise in height, a famous 'shortie' in real life, compared to the door height of your intended purchase, then you're good for 1/22.5. You could, of course, also buy any of the well-known Preiser figures that ate actually MADE to go with 1/22.5 scale.
Hope this helps.
