Tools & Equipment Calculators & Size Guides
Use these free calculators and size guides to match equipment specifications to the job. Estimate compressor capacity, extension cord gauge, pressure washer output, and shop vac size before you buy or set up equipment.
Extension Cord Gauge Calculator
Estimate a suitable extension cord wire gauge from load and distance.
Open calculator →Pressure Washer PSI Calculator
Match pressure washer PSI and GPM to the cleaning job.
Open calculator →Shop Vac Size Calculator
Match wet/dry vacuum size and power to the cleanup job.
Open calculator →Choose the right equipment calculator
Use the air compressor calculator when a pneumatic tool has CFM and PSI requirements. Use the extension cord calculator when distance and electrical load affect wire size. For cleaning equipment, start with the pressure washer tool for outdoor washing jobs or the shop vac tool for wet and dry cleanup.
Why matching specifications matters
Equipment performance depends on more than a single headline rating. Airflow, pressure, electrical load, cord length, tank size, and cleanup volume can all change what is practical. Projectlyst helps narrow the starting range so you can verify the final choice against tool labels, manuals, and job conditions.
Planning guidance only. Verify equipment ratings, electrical requirements, manufacturer instructions, and job-site conditions before use.
