What size bear spray canister should I buy?

Across the reviewers we read, larger canisters (9–10 oz) are preferred for grizzly country because they offer 7–8 seconds of continuous spray and 40-foot range, while 7.9–8.1 oz canisters are lighter to carry and still hit the 30–32 foot mark most experts consider the minimum. Specialist-subreddit consensus on r/camping leans toward the bigger can if weight isn't an issue.
