8 x 6 ft is the most popular shed size, and can feature an apex or pent-style roof. Other common dimensions include: 6 x 4 ft, 8 x 4 ft, 10 x 4 ft and 10 x 6 ft. Please note, larger and smaller designs are available.
Both roof styles are designed to let any water run straight off. However, because apex roofs have two slopes and allow water to run off the quickest, these are believed to be the best roof style.
