How do I choose the right size dehumidifier for a large warehouse space?

I was sitting at home and thinking about dehumidifiers again because my cousin was talking about warehouse storage and she said choosing the wrong size machine can create big problems in humidity control.

I checked Alibaba while scrolling on my phone and searched industrial dehumidifier size calculation warehouse use and I saw many options with different capacity ratings like liters per day extraction airflow coverage area and compressor power. Some machines were designed for small storage rooms while others were built for large warehouses with high moisture levels. I also noticed guides saying size depends on warehouse area ceiling height humidity level and airflow circulation and I is trying to understand how businesses calculate the right capacity instead of just guessing based on size.

Now I feel choosing the right size is not just about buying a big machine but about matching capacity with real conditions because an undersized machine will not control humidity and an oversized one can waste energy and increase cost and I dont want to think bigger is always better without checking actual requirements.

Do you think calculating capacity based on space and humidity is enough or real testing is needed to choose the right dehumidifier size?
