What's useful to hear about
- Errors in the maths. If a calculator is giving you an answer that feels wrong, tell us what you entered and what came back. We'll check it.
- Calculators that should exist. If you went looking for a calculator and couldn't find it here (or anywhere else), that's a great tip.
- Regional quirks. Product sizing and naming varies around Australia — if we've assumed something that doesn't match what your local yard sells, let us know.
- Accessibility or display issues. If something's broken on your phone or with a screen reader, we want to fix it.
What we can't do
- Design your garden. We're calculators, not landscape designers.
- Recommend a supplier. We don't have paid partnerships with any landscape yard or big-box retailer. For local recommendations, ask in a gardening group or check Google reviews.
- Give professional advice. For bigger jobs — retaining walls over 1m, anything involving drainage, structural work — please talk to a qualified tradie or engineer.
Response times
This is a small independent site, so replies come when we can get to them — usually within a week. If it's a calculator bug affecting a real purchase decision, flag it in the subject line and we'll look at it faster.
