who really cares, i hate when park staff tries to claim shit though, i was at a mtn last year, im not going to tell you the name, but it starts with sugar and ends with bush, and i was talking with park staff and they were claiming a 35ft table to be 60, it just made me mad. Anyways, you measre from the end of the lip to the knuckle, just eyeball it

Uh well a 50 foot jump would have 10 more feet of deck than a 40 foot jump.

More like lip to where you aren't going to kill yourself, the sweetspot is normal just a bit lower...

why not take your skis off and use them to measure the deck in ski lengths?
  Don't forget to subtract 4cm per ski for the tips and tails.

jump length = (ski length)x(number of skis) - (number of skis)x(4cm)

this thread is good, I never know how they're measured. I'll still suck at it though. for me it's jumps that I'll hit, and jumps that are fuckin' huge. (sad part is they're not even that big... haha.. sigh)

due to everyones general overestimation of jump size, I think a general rule of thumb similar to that of judging wave size in hawaii should be implemented...simply take the number you think the jump is in feet and divide by 2...

the correct formula is:
(length from lip to knuckle) x 1.5 + n
where n is an arbitarily chosen constant

i'll do an example. say we have measured a jump to be 40ft from lip to knuckle, and n has been randomly chosen to be 24.8. the formula becoms
40x1.5+24.8 = 84.8ft
this turned out great! we now have an 80+ foot jump!

you measure lip to knuckle, but you go further than the deck. so, on a 40 footer (lip to knuckle) you actually probably go between 45-65 ft, depending how the landing is built. but you still refer to it as a forty footer.

get a range finder like the golfers use. stand on the knuckle.  NOT THE SWEET Spot.  And point it at the edge of the jump.  OH dont have one. get some string and have your buddy help out.  KNUCKLE to end of jump. NOT THE SWEET SPOT

I've always thought the right way was lip to knuckle, but it seems to me a lot of people measure lip to sweet spot.

And other mountains simply do run-in to sweet-spot and call it a 50 footer.

It is where the jump goes from flat to slope...where the landing first starts.

Ask people how big it is then subtract one third.

if you're a snowboarder who probably can't hit the jump in the first place, you have to add 50 feet to the true length.


otherwise if you ski, then you just tell the truth!

I found it works perfectly by the rule of 3

ask 2 park staff how big it is, add them together then divide it by 3
works like a charm :P

I usually judge jump length in comparison to something else. i.e. my house, which, being 2 stories and having a pretty steeply peaked roof  is about 28 feet tall at it's highest point. I just imagine my house being tipped on its side and then compare how long the jump table is in comparison. so far at my home mountain i have yet to come across a jump that is that long.
