Why Your Lawn’s Square Footage Matters
Under-applying or over-applying lawn products is a waste of time and money. Knowing your square footage is critical for:
- Fertilizing: Applying the correct amount of fertilizer is essential for a healthy lawn. Too little has no effect, while too much can burn and damage your grass. For a complete guide, see our article on Lawn Fertilizing.
- Pest & Weed Control: Product effectiveness depends on the correct application rate. Learn how to protect your lawn in our Lawn Pest Control guide.
- Seeding: Whether starting a new lawn or overseeding an existing one, you need to know your area to buy the right amount of grass seed.
- Choosing the Right Tools: Your lawn size is the biggest factor when choosing equipment. A large lawn might justify one of the best robotic lawn mowers, while a smaller yard needs a more compact tool. See our guide to the best lawn tools for 2025 to build your perfect toolkit.
