There is no method, as it was removed in the conversion from 3.5e to PF. Why does it matter? You're going for length not height.
Perhaps he has a restrictive GM who is saying a jump can't be completed due to low ceilings blocking the ability to clear a long distance...
Obviously, people don't jump without a change in elevation...

There can't be a simple set of rules for this. For instance, for every +10 speed you have above 30, you get a +4 for your jump rolls. Someone with a base speed of 30 is going to have to put more force into their jump and will have to jump up somewhat to jump a distance of 20. Someone that has a base speed of 80 won't have to jump up nearly as high because they've got more momentum and don't need as much upward force to counteract gravity as gravity will be acting on them for a less amount of time (gravity without the force of the ground to counteract it..obviously gravity is always acting on them).
Obviously this is using real world physics, but there aren't defined game mechanics for it. While "1/4 of the vertical distance" may be sufficient, it should be somehow modified for faster/slower creatures in much the same way jump is modified for those creatures.

I get what you are saying.
Unfortunately, for ease of play, a standardized formula, put forth as errata, or a FAQ, is best for most games.
This is a frequently asked question, and whilst it may seem to fall into the "common sense" category, I have seen a number of different opinions/rulings, and many of those were considered "common sense" to the individual/individuals' point of view.

Well with a physics/math approach, what I think would make the most sense is to assume the character jumps at a 45 degree angle to give the longest possible jump. Then take 1/2 the length jumped. Then 1/2 length times the tangent of 45 degrees which is 1. So the max height in a jump should be 1/2 the length? Math isn't a strong suit, nor is this RAW.

Chess Pwn wrote:a long jump is 0 height, if you want some height then you're also doing a jump up.You do understand how silly that sounds, and though no written rules dispute it, no written rules support it.
So, that is why I suggest hitting the FAQ button.
A horizontal long jump would work for a kung fu master. Interesting there's no set rule.

Looking at some sample real-life data - I haven't verified these numbers:
An Olympic long jumper might be capable of jumping 8.5m - in Pathfinder terms, 20-25 feet.
The time he is in the air is 0.88 seconds.
(Note that this is way faster than 30 foot movement - anyone trying to do a serious long jump is going to be sprinting at top speed, not just doing a double-move hustle.)
You can work out how high he jumps from the time spent in the air - half way though the jump he will be at his highest, and then will fall at a fairly normal rate for the remaining 0.44 seconds.
Using s = ut + att/2
Distance travelled = (initial speed of 0) + (0.5 * 9.8m/s gravity * (time of 0.44 seconds squared)).
This gives a distance travelled (fallen) of 0.95 metres.
So at the peak of his jump, he's about three feet up in the air.
This should actually be a bit lower due to air resistance.
A shorter jump won't need to go as high as that.

I mean, 1/4, you know.
Assuming you're only 2.5 feet tall.
Otherwise, trying to jump 7.5 feet up in a 10 foot high corridor might be painful.blackbloodtroll |
My view is to divorce this from real physics and common sense, and run it like Chess Pwn suggested.
A long jump has 0 height. A high jump has 0 length. If you want to jump both out and up then you need enough jump distance to cover both the length and the height.
Running it like this has some serious drawbacks.

Check out the Aerial Assault path ability:
"Aerial Assault (Su): You can charge at creatures in the
air, or leap across obstacles as part of a charge. When
making a charge attack, you can expend one use of
mythic power to include a single Acrobatics check made to
jump, adding 10 feet per tier to the height or distance you
jump. You take no falling damage from the height gained
as part of this leap. If your attack hits, you may deal an
amount of additional damage equal to the falling damage
appropriate for the height you reached. Alternatively, you
may replace your melee attack from this charge with a
grapple check. If you succes sfully grapple a creature, you
bring it to the ground with you at the end of your jump,
and it takes an appropriate amount of falling damage for
the height it was at when you grappled it."
They made height equivalent to distance as a choice, with an Acrobatics check, but then gave damage for the height.
So you could infer you normally don't travel high enough to earn that damage on a leap.

Use the guidelines in the Acrobatics skill (a horizontal jump's peak height is one-fourth of the horizontal distance) to determine whether a character can make a jump.Holy crap! That's hidden.
Thank you so much.
I have good memory, and I read the CRB cover to cover. [Maybe not all the spells, ...] Also, I have quoted it several times. It is in the same area of rules as 3.5.
No FAQ required.
PFS RAW is in CRB.

I'm going to go out on a limb here and say that this isn't RAI. It appears that they intentionally deleted it from the acrobatics section but inadvertantly left it in within the environment section. it does need to be updated and put properly in the Acrobatics section.

Long Jump to an elevated point.Long Jump to jump over an obstacle, like a hurdle.
For these two, which DC is higher, the distance or the elevation. Use the higher DC and the other one should be good. GM is free to add in an additional circumstantial penalty of course. I would if the DC on both was close to the same.
e.g, 20' distance, 1' height, I wouldn't care about the height.
5' distance and 1' height? I might add a +1-2 to the DC.
