Mulch Calculation Formula:
From: | To: |
The Mulch By Yard calculation determines how much mulch you need to cover a specific area based on the coverage rate of the mulch product. It helps you purchase the right amount of mulch for your landscaping project.
The calculator uses the following equation:
Where:
Explanation: The equation divides the total area by how much area one cubic yard of mulch covers to determine the total cubic yards needed.
Details: Calculating the correct amount of mulch prevents over-purchasing (saving money) or under-purchasing (requiring additional trips to the store). It also ensures proper coverage depth for optimal plant health.
Tips: Measure your area in square feet. Standard mulch coverage is about 324 ft² per yd³ at 1-inch depth (100 ft² per yd³ at 3-inch depth). Adjust coverage rate based on your desired depth.
Q1: What's the standard coverage rate for mulch?
A: Typically 324 ft² per yd³ at 1-inch depth, or 100 ft² per yd³ at 3-inch depth.
Q2: How do I measure my area?
A: For rectangular areas, multiply length by width. For irregular shapes, break into smaller rectangles and add them together.
Q3: Should I account for existing plants?
A: Yes, subtract areas occupied by plants or other features that won't be mulched.
Q4: How much extra should I buy?
A: Consider buying 5-10% extra to account for settling and irregular application.
Q5: Does mulch type affect coverage?
A: Finer mulches may cover slightly more area than coarse mulches at the same depth.
