YARC — Yet Another Rack Calculator. Free network rack calculator for structured cabling, patch panel mapping, and data center infrastructure planning. Design rack layouts and calculate precise cable lengths.

Why I Built YARC I built YARC to solve a problem that cost me time and money on every job site: showing up with the wrong cables. Wrong lengths, wrong quantities, missing cable managers — it all led to messy installations and wasted trips. My planning was a nightmare of spreadsheets and guesswork. YARC fixes this. Plan the rack visually and get a precise packing list every time. But the part I always missed in every other tool was the Inventory function — the ability to document what every port connects to, mark ports as NC (not connected) or NA (not available), and generate a full port-level patching schedule that a technician can actually use on site. Every rack should have a living document. YARC is that document.
