Standard one-octave G major fingering uses 1-2-3-1-2-3-4-5 in the right hand and 5-4-3-2-1-3-2-1 in the left hand. The notes are G, A, B, C, D, E, F♯, and G, so only F♯ lands on a black key.
If you already know the G major scale and chords, the piano-specific job is hand movement rather than note discovery. Learning how to play the G major scale on the piano becomes much easier once the crossing points are treated as prepared movements instead of emergency reaches under the palm.
The G major scale piano notes stay the same in both hands, but the fingers do not cross at the same place. A useful G major scale piano hand position keeps the wrist free to travel sideways while the fingers stay close enough to the keys that F♯ does not become a separate little jump.
The black key is not the difficult part. Finger 4 reaches F♯ naturally when the hand has already moved forward with the scale, and the meaning of a sharp note is simply a pitch raised by a semitone. Trouble usually starts when the wrist stays parked over the first G while the thumb tries to tunnel toward C.
A G major 5-finger pattern is different from the full octave scale. Playing G-A-B-C-D with 1-2-3-4-5 can be useful for early coordination, but it does not teach the thumb crossing required for a complete G major scale piano one-octave run.
The G major scale piano descending route reverses the movement. From the upper G, use 5-4-3-2-1 through G-F♯-E-D-C, then bring finger 3 over to B and finish with 2 on A and 1 on G. Isolating C-B-A-G for a few repetitions often fixes a rough descent faster than replaying the whole octave.
This is the same basic movement logic used in C major scale fingering for both hands, but G major gives finger 2 the raised seventh on F♯. If you are working on how to play the G major scale on the piano with the left hand, isolate D-E-F♯-G until the crossover stops producing an accent or hesitation.
A G major scale piano both hands exercise gets messy if both crossings are learned at once. Practice each hand separately first, then combine four-note fragments at a slow, steady pulse. The right hand moves its thumb after B, while the left hand makes its main crossover after D, so trying to think one command for both hands usually creates unnecessary tension.
Black-key-heavy scales can use quite different routes, which is why B major scale fingering on piano starts the left hand with finger 4 rather than copying the G major start. Standard fingering is a physical solution to the keyboard layout, not a rule that every major scale must begin with the same fingers.
The G major scale piano finger position for 2 octaves in the left hand also changes around the middle G. The thumb can reach that G, then finger 4 crosses to A so the second octave can continue. Practicing only the notes around the octave boundary is more useful than repeatedly restarting from the lowest G.
Good G major scale piano practice also varies rhythm and articulation while keeping the fingering fixed. Short-long pairs, long-short pairs, legato, and light detached notes expose uneven crossings without forcing more speed. Playing the G major scale on the piano should eventually feel like one continuous hand route rather than two chunks joined by a thumb maneuver.
Once the movement is reliable, use the scale inside actual harmony. The G major chord progressions that resolve cleanly give those same notes changing harmonic roles, which makes scale practice less mechanical because G, B, and D stop being merely positions under the fingers and start behaving as chord tones.

The right hand crosses after B
For the G major scale piano right hand, start with finger 1 on G, 2 on A, and 3 on B. Bring the thumb to C, then continue 2 on D, 3 on E, 4 on F♯, and 5 on the upper G.The black key is not the difficult part. Finger 4 reaches F♯ naturally when the hand has already moved forward with the scale, and the meaning of a sharp note is simply a pitch raised by a semitone.

The left hand moves over the thumb
For the G major scale piano left hand, place finger 5 on low G, then play A, B, C, and D with 4-3-2-1. Finger 3 crosses over to E, finger 2 takes F♯, and the thumb finishes on the upper G.This is the same basic movement logic used in C major scale fingering for both hands, but G major gives finger 2 the raised seventh on F♯.

Two octaves change where the scale continues
A G major scale piano 2-octave run cannot treat the middle G as a finish line. In the right hand, use finger 1 on the middle G instead of 5, then continue A-B-C-D-E-F♯-G with the same crossing logic before ending with finger 5.The G major scale piano finger position for 2 octaves in the left hand also changes around the middle G. The thumb can reach that G, then finger 4 crosses to A so the second octave can continue.
