Your purchase notes
Keep the details in one place.
Look at burner positions as well as burner count. The layout matters when two wide pans need to sit alongside each other.
Put the dimensions of the pans you use together beside the hob drawing. Check the worktop cut-out and the clearances given for the exact model.
Space and clearance checker
Check one dimension at a time using measurements you have verified. Enter the clearance from the exact product instructions; this calculator does not decide a safe installation allowance.
