Gap Jump

Cover maximum horizontal distance by jumping at full run speed from the exact edge of a platform. The baseline skill every other technique assumes.

Also known as: long jump, running jump, distance jump

What it is

A gap jump is the simplest technique on this list and the one people most often get wrong, because horizontal distance in Roblox comes almost entirely from the speed you already had when you left the ground. There is no in-air acceleration to save you. If you jump from a standstill and then press forward, you travel far less than if you were already at full run speed at the moment of takeoff.

Two things determine whether you clear a gap: your speed at takeoff and how close to the edge you jumped from. Both are fully under your control and neither requires timing precision, which is why gap jumps reward preparation rather than reflexes. Back up far enough to reach full speed, run at the gap, and leave the ground at the last possible moment.

Roblox's default humanoid runs at WalkSpeed 16 with JumpPower 50 under gravity 196.2, which produces a fairly generous arc. Games override these values freely, so a gap that is trivially clearable in one obby may be genuinely impossible in another with reduced jump power. If a gap looks like it should be reachable and consistently is not, consider that the game may have changed the numbers rather than that you are jumping badly.

The inputs, step by step

  1. 1

    Back up to build runway

    Walk backward from the edge until you have several character-lengths of space. You need enough distance to reach full speed before takeoff.

  2. 2

    Square up to the gap

    Face directly across the gap. Any angle in your approach converts forward distance into sideways drift you do not want.

  3. 3

    Run at full speed

    Hold W the whole way in. Do not tap, and do not slow down as you approach the edge — the instinct to hesitate is what causes most short jumps.

  4. 4

    Jump at the edge

    Press Space as your character reaches the last stud of the platform. Jumping early wastes distance; jumping late means you have already stepped off.

  5. 5

    Hold forward through the arc

    Keep W held for the whole flight. It will not accelerate you, but releasing it can cost you the tail of the arc.

  6. 6

    Land and keep control

    Expect to keep moving forward on landing. If the landing platform is small, be ready to release W immediately.

Timing notes

  • Horizontal distance comes from takeoff speed. There is no meaningful mid-air acceleration in default Roblox movement.
  • Jumping one stud early costs you roughly that stud at the far end. The edge is the target, not a safety margin.
  • If a gap is unreachable at full run speed from the exact edge, it is probably not intended to be crossed with a plain gap jump — look for a truss, a headhitter, or a wall to catch.

Common mistakes and how to fix them

Jumping from a standstill and pressing forward in the air.

Build speed on the ground first. Air control does not add distance in default Roblox movement.

Slowing down instinctively as the edge approaches.

Commit to full speed through takeoff. Hesitation is the single most common cause of a short gap jump.

Jumping well before the edge to feel safe.

Every stud you leave behind is a stud you lose on the far side. Take off from the last stud.

Approaching at an angle.

Square up first. A diagonal approach spends part of your speed travelling sideways.

Assuming an impossible gap means bad technique.

Games can lower jump power. If a gap fails from a perfect full-speed edge jump every time, the route probably needs a different technique.

Gap Jump FAQ

Does holding forward in the air make me jump further?

Not meaningfully. Default Roblox movement gives you steering in the air but not acceleration. Your distance was set at takeoff.

How far can a default Roblox character jump?

With Roblox's defaults — WalkSpeed 16, JumpPower 50, gravity 196.2 — a full-speed edge jump clears a comfortably wide gap, but the exact figure depends on those three values, and any game can change all of them. Treat published numbers as approximations and test in the game you are playing.

Why do I clear the gap in one obby and not another that looks identical?

Because the numbers differ. Jump power, walk speed, and gravity are all per-game settings, so visually identical gaps can have different difficulty.

Jump Chaining (Holding Space)

Easy

Holding the jump key makes the character jump again the instant it registers a landing. This is the engine behaviour that every wall technique is built on top of.

Truss Hop

Hard

Jump off a truss or ladder to gain height faster than climbing it, or to cross to a surface the ladder does not reach.

Headhitter

Hard

Interrupt a rising jump by hitting a ceiling, causing the character to land immediately and jump again. Used to quickly regain height after an overshoot.
