Should I get a 1 gallon or 2 gallon sprayer?

Whether you should get a 1-gallon or 2-gallon sprayer depends on your yard size, how often you spray, and physical comfort, as both have advantages. A 1-gallon sprayer is lighter, more compact, easier to carry with one hand, and better for small areas under 1000 square feet, indoor pest control, spot weed spraying, and precise application around delicate plants. It is less tiring, easier to store, and cheaper, typically 15 to 25 dollars. However, it requires frequent refilling if you have larger area, and you may need to stop and refill multiple times. A 2-gallon sprayer holds double the liquid, covers about 2000 to 4000 square feet per fill depending on application rate, requires fewer refills, and is better for medium gardens, lawn weed control, and perimeter pest treatments. It is still manageable to carry, around 15 pounds when full, and costs only slightly more, 25 to 40 dollars. Most homeowners find 2-gallon is the sweet spot for versatility, as it can do small jobs with partial fill and larger jobs without constant refilling. If you have very small patio garden or indoor use, get 1-gallon. If you have typical suburban yard or larger, get 2-gallon. Many people own both, 1-gallon for indoor and 2-gallon for outdoor.
