## How to use these tools
Each tool starts from two or three things you already know — a room or lawn size, a budget, a utility bill — and turns them into a shortlist of telescopes instead of a wall of specs. Nothing is submitted: the calculation runs in your browser, so you can try a few combinations before you commit to a model.

- Start with the tool that matches the decision in front of you, not the biggest one.
- Write the result down, then check it against the full comparison chart — the tool narrows the field, the chart shows the trade-offs.
- Re-run it when your assumptions change (budget, room size, household size). A different input often changes the pick.
