The calculation, without hidden assumptions
Seed recommendations are species- and job-specific, so MAXScanner does not hide a universal rate. Enter the new-lawn or overseeding rate from the seed label or your agronomic plan, and the calculator handles area scaling and package rounding.
How to use this calculator
Measure the seedable lawn area.
Enter the lb/1,000 ft² rate appropriate to the exact seed and whether this is establishment or overseeding.
Set bag weight and optional allowance to produce a whole-package order.
Where people use it
- •New lawn establishment
- •Overseeding
- •Comparing seed package sizes
Worked example
At 8 lb per 1,000 ft², a 5,000 ft² lawn needs 40 lb before allowance.
What the result does not assume
- •The calculator does not prescribe species or seeding rate.
- •Germination, site preparation and timing are outside the quantity model.
Frequently asked questions
Can I use this for overseeding?+
Yes. Enter the overseeding rate from the product or local recommendation.
Why is the rate not fixed?+
Different grasses and establishment methods use different rates.
Is the seeding rate a recommendation?+
No. The rate is an input. Use the seed label or an agronomic recommendation for the species, climate and whether the work is new establishment or overseeding.

Keep the result connected to the real job
MAXScanner keeps the formula and assumptions beside the result so you can verify the number before using it in a drawing, estimate, specification, worksheet or document. Where a supplier, manufacturer, drawing or applicable standard owns a requirement, that source remains authoritative.
