All guesstimates
ChallengingMarket Sizing
Estimate the number of cricket bats sold in India every year
Scope it first — questions to ask
- · All bats — tennis-ball, season, kids' — or professional-grade only? — Scope: all bats.
- · Sold new in a year (not the stock in circulation). — Scope: annual new sales.
Assumptions on the table
- · Cricket-playing age (8–30) ≈ 35% of 1.4B ≈ 490M
- · ~15% play with some regularity (gully + school + club) ≈ 74M players
- · Bats are shared: ~1 bat per 3–4 regular players → stock ≈ 21M bats
- · A bat lasts ~3 years on average (tennis-ball bats longer, season bats shorter)
