I've searched all over, but I can't find the standard length for a road fork from drop-out to crown. If I had a road bike I could measure it, but I don't, so could anyone tell me this? Thanks :)

There is no standard.

If the fork is too long, the dropouts will be lower than the hub. If it is too short, the wheel will not reach the ground. :rolleyes:

Mine is 14 inches from the bottom of the drop-out to the inside top of the crown. That is in a straight line. (does't account for the curve).
Hope this helps.

Thanks, Soberone. What brand/model fork do you use?

A direct-line measure from the centre of the brake bolt hole to the centre of the dropout may be more useful. You can compare the drop required for the brakes (ie tyre clearance), which is variable.
Road caliper brakes are available in standard (ie small), medium and long drop, for different amounts of tyre and fender clearance.
It is not a published figure for any fork.

The only thing that matters is that the fork is designed for the correct wheel size which for road bikes is 700c, which is not an actual measurement, but a size designation. FWIW, 700c rims are actually 622 mm.

It also matters how much clearance you have between the rim and the brakes. If you want to fit wider tyres or fenders (eg for winter training), you need a longer fork.
If you just want a standard racing fork for a standard groupset brake and a racing tyre, then any old 700c racing fork will fit.
If you want to fit a 28mm tyre or fenders, better take note of the clearance.
