Both ほど and くらい express extent, but ほど often implies a higher degree or a limit, while くらい is more about an approximate extent. ほど is more common in negative sentences (e.g., これほど難しいとは思わなかった 'I didn't think it was this difficult'). くらい can be used more casually for 'at least' (e.g., それくらいできる 'I can do at least that much').
English often uses 'extent' in phrases like 'to the extent that...' which in Japanese is usually expressed with ほど or くらい attached to a verb/adjective, not a separate noun. Avoid direct translations like 範囲まで unless you mean physical scope.
