About DeviceCalc
DeviceCalc is a calculator-first website for practical device, screen, appliance, and setup decisions. The goal is simple: help people estimate the right size, distance, capacity, cost, power, brightness, or fit before they buy, install, or use a device.
What We Build
DeviceCalc focuses on useful calculators, not generic content pages. Each calculator is designed around a real user task: choosing a TV size, checking projector placement, comparing phone screens, estimating storage, or sizing a room device.
The first version started with TV calculators and has expanded into projector, monitor, phone, and air conditioner tools. New topics are added only when the calculation can help with a concrete buying, installation, comparison, or running-cost decision.
How We Keep Pages Useful
- Every calculator explains the formula or method behind the result.
- Results are presented as planning estimates, not guarantees about a specific product.
- Specific answer pages must solve a real question and link back to the full calculator for custom inputs.
- Pages should show assumptions, limitations, examples, and related tools instead of repeating the same wording.
