How many feet of string lights do I need for a typical patio?

Across the reviewers we read, a standard 12x12 to 15x20 ft patio is usually covered by a 48–100 ft strand depending on how many crossings or zig-zag passes you want. Larger backyard perimeters and pergolas push reviewers toward the 200–300 ft commercial-grade strands. Always measure your run including any sag (10–15% extra) and confirm the strand supports end-to-end connection if you plan to chain multiples.
