Modulargrid is the standard tool for planning a Eurorack system — it tracks cost, power draw, HP, and module placement before purchase

Modulargrid (modulargrid.net) is a free online tool that lets users virtually build and plan Eurorack systems. For each hypothetical module, it shows cost, current draw on +12V/-12V rails, HP width, depth, and allows arrangement in a virtual rack. The platform’s database covers thousands of modules with specifications. It is the standard resource used before purchasing to avoid buying modules that don’t fit physically or draw too much power. Modulargrid also has a community browsing feature — you can browse other users’ systems by genre or use case to get inspiration.

Examples

Before purchasing: add planned modules to a Modulargrid rack, check that total +12V draw is under 80% of supply capacity, verify all modules fit in HP, compare costs. Adjust before ordering.

Assessment

Name three pieces of information Modulargrid provides about a module. Explain how you would use it to verify that a 6-module system fits in a specific case and doesn’t overload the power supply.
