Using the common Roblox build scale, 1 stud is about 0.92 feet. So:

  • 9 feet is about 9.8 studs
  • 14 feet is about 15.2 studs

Quick math

  • 9÷0.919≈9.89\div 0.919\approx 9.89÷0.919≈9.8
  • 14÷0.919≈15.214\div 0.919\approx 15.214÷0.919≈15.2

Simple answer

So 9 to 14 feet is roughly 10 to 15 Roblox studs.

Note

Some Roblox builders also use a rough 1 stud = 1 foot shortcut, but the more physics-based conversions put a stud closer to 0.28 meters , or about 0.92 feet.
