What this calculator is
Practical planning, not paperwork. The Fireplace Hearth Pad (3D) on MyCalcsWorld is built for dinners, trips, and weekend projects with numbers you can tweak instantly. What it does: Hearth pad width, area, and volume from opening size, front depth, and side extensions — 3D hearth. Typical inputs: Opening width (m), Opening height (m), Hearth depth (front) (m), Side extension each (m), Pad thickness (m). Demo defaults (opening width 1 m, opening height 0.75 m, hearth depth (front) 0.5 m, side extension each 0.2 m, pad thickness 0.05 m) currently resolve to Hearth width 1.40 m in the live panel — change any field to explore sensitivity. Who it helps: households splitting bills, road-trippers estimating fuel, DIY planners, and anyone doing practical day-to-day arithmetic.
When to use / who it helps
- Ordering hearth stone.
- Checking pad width vs opening.
- Estimating pad volume.
- Use the Fireplace Hearth Pad (3D) for dinner splits, trips, DIY lists, and other practical planning.
- Treat the number as a plan, then round in a way your group or project agrees on.
How to use
Steps
- Enter opening, hearth depth, side extensions, thickness.
- Read pad width/area/volume.
- Orbit the hearth.
- Open the Fireplace Hearth Pad (3D) on MyCalcsWorld and skim the labeled fields before you type.
- Set Opening width (m) — demo default is 1 m.
- Set Opening height (m) — demo default is 0.75 m.
How to interpret results
- Clearance box is a rough visual volume only.
- Opening area is width×height.
- Pad volume for material takeoff.
- Each result is driven only by the labeled inputs (Opening width (m), Opening height (m), Hearth depth (front) (m), Side extension each (m)); anything not on the form (fees, holidays, clinical adjustments) is outside this estimate.
- Tip and split tools show exact arithmetic; decide how to round coins in your group’s favor.
Common mistakes & gotchas
- Ignoring side/front code minimums.
- Using for gas vs wood without checking rules.
- Forgetting thickness.
- Forgetting to agree how to round coins or tip when splitting among friends.
- Ignoring waste factors on DIY quantities when the form labels them separately.
Worked example
Worked example — 1 m opening, 0.5 m depth, 0.2 m sides, 0.05 m thick
- Hearth width = 1.4 m.
- Area = 0.7 m².
- Volume = 0.035 m³.
- Open the Fireplace Hearth Pad (3D) (fireplace hearth 3d) and note the starting defaults (opening width 1 m, opening height 0.75 m, hearth depth (front) 0.5 m, side extension each 0.2 m, pad thickness 0.05 m).
Result: With defaults (opening width 1 m, opening height 0.75 m, hearth depth (front) 0.5 m, side extension each 0.2 m, pad thickness 0.05 m), the Fireplace Hearth Pad (3D) shows: Hearth width 1.40 m.

How to calculate / formula
Hearth width = opening + 2×sideExtension. Area = width×hearthDepth. Volume = area×thickness. Everyday estimators combine simple arithmetic with conventional rules of thumb (splits, tips, DIY material allowances, fuel math). Treat outputs as planning aids, not contractor quotes, tax filings, or binding agreements. For the Fireplace Hearth Pad (3D), the labeled fields (Opening width (m), Opening height (m), Hearth depth (front) (m), Side extension each (m)) drive the live result panel.
Frequently asked questions
Code clearances?
Follow local fire code; tool is pad geometry.
Raised hearths?
Thickness is the pad only.
Corner fireplaces?
Approximate with opening width.
Why 3D?
To see pad vs opening.
What does the Fireplace Hearth Pad (3D) on MyCalcsWorld actually compute?
Hearth pad width, area, and volume from opening size, front depth, and side extensions — 3D hearth. You enter Opening width (m), Opening height (m), Hearth depth (front) (m), Side extension each (m), Pad thickness (m), and the result panel updates in your browser.
What inputs does the Fireplace Hearth Pad (3D) need?
The Fireplace Hearth Pad (3D) asks for: Opening width (m); Opening height (m); Hearth depth (front) (m); Side extension each (m); Pad thickness (m).
What results does the Fireplace Hearth Pad (3D) show?
The panel reports Hearth width. Each figure is recalculated whenever you change an input, so you can compare scenarios side by side.
