What pitch length and boundary distance apply?

Stage 2 Match Day Rules section 4:

• Pitch: 18 metres stump to stump in all matches. The popping crease is 1.22 metres in front of the stumps.
• Boundary in T20 matches: 40 metres, measured from the stumps at the batter's end.
• Boundary in 30-over matches (measured the same way):

• If the ground is smaller, the home team must maximise the boundary to the extent the ground allows.
• Mark no-go zones behind the bowler's end with cones. Spectators must not enter them except to pass through without disrupting play.
• Keep at least 3 metres between any solid structure (tents, scorers, spectators, chairs) and the boundary.
