Quick answer
Mulch quantity is mostly a surface-area problem. The biggest source of over-ordering is assuming every established bed needs the same depth as a brand-new installation.

Measure the bed area
Break irregular beds into simple rectangles and circles and add the areas together.
Decide whether this is a refresh or new installation
Existing beds often need only enough mulch to restore coverage. New bare beds may need a deeper initial layer.
Calculate cubic yards
Multiply square footage by depth in feet and divide by 27. The product-page calculator can do this automatically.
Keep mulch away from trunks and crowns
Do not use extra material by piling it against trees and shrubs.
Round sensibly
A small overage can help with uneven bed edges, but huge safety factors can create a leftover pile.
- Check existing mulch depth before ordering.
- Fine, medium and landscape mulch have different appearance and handling characteristics.
- Ask about current bark availability before choosing the final product.
