How much can you increase your bideltoid size from training side delts?

[6'3htnnnnn]

6'2 18.75-19 inch bideltoid, I've been going to the gym for 2-3 years , and I've never done lateral raises cause idk why. I do shoulder press though which still has a bit of side delt

Right now 68kg (started at 48kg) , 15-16% bodyfat, 12 inch arms, wondering can I get to 20.5 inch bideltoid? Lean bulking to 74kg rn (+6kg over next 4 months is goal)

Shoulder press is arguably better for side delts than lateral raises

You could add 1-3 cm of growth to your bidlet if you prioritize your front and side delts. If you see that you make no progress for over a year then you can consider roids
