Disclosure: this is our worksheet and app, made with AI assistance. I'm sharing it in the advertising area because it may be useful when gathering equipment details before choosing a generator.
The worksheet is a free, one-page PDF with no signup. For each item, there's space for its model, quantity, voltage, running and starting ratings, and whether it starts automatically. It also asks which items run or restart together, and records a generator's continuous and maximum ratings for the fuel mode you're considering. Keep the relevant label photos or manual pages with the sheet so the numbers can be checked.

A useful way to start is to list the exact equipment you want to keep running, then fill in figures from its label/manual. Leave a missing starting rating marked unknown instead of treating it as zero. That gives your supplier or electrician a clearer list to review.
Our free browser calculator is at
https://generatorsizes.com/. The optional iPhone/iPad app keeps equipment plans offline; its free version gives a complete result for up to four items, with a US $2.99 one-time unlock for larger lists. You do not need the app to use the worksheet.
Important limit: calculator results are planning estimates, not an approval to connect equipment. The startup estimate assumes one motor starts at a time; automatic or overlapping starts can exceed it. Have the actual equipment and installation checked by the appropriate professional.
If you use a different way to collect this information, what is the field you most often find missing?
