ProjectQty is a free collection of construction material calculators for people who need practical quantity estimates without setting up a spreadsheet or creating an account. It is built for homeowners, DIY planners, remodelers, and lightweight construction teams who want to turn real field measurements into order-ready material quantities while still understanding how the estimate was produced.
The site currently includes 41 calculators across common project categories such as concrete, gravel, mulch, soil, roofing, flooring, paint, masonry, fencing, patios, pavers, decking, drywall, and other jobsite planning tasks. A user can enter the measurements they already have, choose imperial or metric units where supported, adjust assumptions like waste allowance or coverage, and then review the calculation instead of only seeing a final number.
ProjectQty is intentionally transparent. Each calculator is designed to show the formula, unit conversions, assumptions, rounding behavior, and quantity logic behind the result. That matters because material planning is rarely just a single answer. A slab estimate may depend on thickness and waste. A gravel estimate may depend on depth and compaction. A flooring estimate may depend on room shape and extra material. ProjectQty helps users see those assumptions before they buy materials, talk to a supplier, or compare estimates.
The product is also lightweight. There is no required sign-up, no complicated project management workspace, and no black-box AI estimate. Users can open the calculator they need, get a result, print or share useful result pages, and keep browser-local project guides for planning. This makes it useful for quick weekend projects as well as repeated estimating work where a small team wants consistent calculations.
ProjectQty is made by Kyle Powell as part of a broader set of practical browser-based tools. The goal is not to create one isolated calculator page, but to build a durable collection of simple tools that solve everyday planning problems with clear math, clean pages, and easy access. ProjectQty focuses on construction quantities first because small estimating mistakes can lead to wasted material, extra trips to the store, or under-ordering that slows a job down.
For Sidehunt users, ProjectQty may be useful as an example of a focused utility product: it serves a specific audience, keeps the core workflow free, exposes the logic behind its answers, and avoids forcing accounts where they are not needed. The best use case is when someone knows the dimensions of a project and wants a fast, defensible material estimate with assumptions they can inspect before taking action.
