Calculator guides
DIY Material Guides
These guides explain the assumptions behind common home material estimates. They are companions to the calculators, not a blog, and they focus on planning depth, thickness, waste factor, unit conversion, and bag or bulk quantity decisions.
How to use these guides
- Read the depth, thickness, or bag-yield assumptions before opening a calculator.
- Use the tables to compare common planning scenarios with real units.
- Open the linked calculator when you need an estimate for your exact dimensions.
What these guides do not replace
- Manufacturer installation instructions, product labels, and bag yields.
- Local building requirements, permits, structural design, or professional advice.
- Store pricing, delivery quotes, contractor estimates, or local labor rates.

Material planning guides
These guides focus on paver base decisions, patio slope, repair symptoms, paver material planning, concrete slab quantity, slab thickness, and mulch depth because those inputs change material quantity quickly and are easy to misunderstand.
Use this quick depth checklist before estimating gravel, bedding sand, compaction overage, and total paver project materials.
Pavers guide Paver Patio Slope Guide: How Much Drop Away From the House?Check common paver patio slope ranges, convert slope to total drop, and note drainage risks before estimating base materials.
Pavers guide Why Are My Pavers Sinking?Match sinking, rocking, low edges, joint washout, and drainage problems to likely causes before planning a repair material list.
Pavers guide Can You Lay Pavers on Sand Only?Use this decision checklist to separate bedding sand from structural base material before planning a patio, walkway, or small reset.
Pavers guide Paver Patio Material ChecklistUse this material-first checklist to prepare planner inputs for base gravel, bedding sand, paver count, edge restraint, joint sand, and overage.
Pavers guide How to Clean Paver Joints Before Re-SandingCheck joint depth, debris, weeds, loose pavers, drainage, and normal new paver gaps before adding joint sand or polymeric sand.
Concrete guide How Much Concrete for a 10x10 Slab?Compare concrete volume and bag counts for a 10 ft by 10 ft slab at common planning thicknesses.
Concrete guide Recommended Concrete Slab Thickness for Patios, Sheds, and DrivewaysLearn how slab thickness affects concrete volume, bag count, and planning assumptions before estimating material quantity.
Mulch guide Mulch Depth GuideUse this guide to compare mulch depth, cubic yards, 2 cu ft bags, and settling overage before estimating a landscape bed.
Guides help you choose inputs
A calculator answers the quantity question after you enter dimensions. A guide explains why an input matters before you choose it. For example, a paver base calculator can convert depth into cubic yards and tons, but a depth guide helps you understand why a patio, walkway, and driveway should not all start with the same gravel layer.
