Well, if it's for 1/24th or 1/25th cars it should have the same scale on the box.

If you want to scratchbuild the garage just divide everything by 1/24th etc. Or find a 1/24th scale figure and just eyeball it.

As to a garage diorama parts you might want to ask over on the auto forum, mostly military guys here.

1/24 is the same as 1/2" = 1'-0" scale. so, to scale, an 8 x 8 garage door is 4" x 4". A 10' tall door is 5" tall. A service station garage ceiling is about 12' tall, so that's 12/2 or 6". We can derive some numbers, too. 1/4" = 6"; 1/8" = 3" 1/16" = 1.5" and 1/32" = 3/4". To use round numbers, .040" ≈ 1" You could use 3/8" stock to represent 8" CMU walls. You could be forgiven for modeling 8x16x8 concrete block as 9x18x9, or 3/8" x 3/4" x 3/8"--the difference will be a portion of a 32nd of an inch. Unless you want to cut .318 x ..636 .318" blocks and fit them up with 1/64" (3/8" at scale ) mortar joints.

Well explained instructions CapnMac...could not be clearer

Are your cars die-cast or built plastic kits? 

Die-cast: Phoenix Toys - Hobby Gear product line in 1/24 can match with your vehicles.

Styrene / resin models: Fujimi makes a lot of Garage & Tools series kits to build.

Maybe this will help: www.walthers.com www.micromark.com

These are both sites that cater specifically to modeling. They both offer specialized tools, models, and modeling accesories, and other modeling assortments.

The only thing I would suggest is which ever scale you can find the most after market products in is the scale of auto you should use. I know that may limit your choices, but it may be worth considering.
