Greetings. A quick trivia question from someone with no experience with model trains. WHAT is the width, in milimeters, between the tracks in HO
scale?? (Obviously we don’t have a sample of HO track handy or we’d measure it myself.) We purchased 3 sets of toy trains during a close-out sale at KB toys for our 5-year-old son. The sets came with their own track … molded in plastic.
We’re working on a small layout and rather than taking our dremel tool to the existing toy track and modifying it for a pair of scratch-built
bridges, we were hoping that we could add some conventional HO scale track to supplement the toy set’s track. Any assistance would be appreicated. - Eric
Hi James,
Acknowledged. Thank you. It doesn’t look like we’ll be having a problems.

HO is 3.5 mm to the foot. Standard track is 4 foot 8 inches so that calculates to 16.333329 mm.
Hope that helps…Walt
Eric, just measured a piece of track. Looks like 16mm or 16.5mm. Just did it real quick, but that should be close enough. Welcome to the world of trains…Jamie
Walt, standard gauge track is 4 ft. 8.5 in. and can be as wide as 4ft. 9 in. and still be considered in gauge. It can’t be any narrower though. HO track is 16.5 MM by convention. BTW, this was posted twice and was already answered on the other post.
