Does building a Cardano node on testnet takes less storage than mainnet?

If so, what are the approximate storage requirements?

2 Answers 2


Yes, the testnet takes less storage. This is what I got when I installed them a month ago:

Testnet: 11 GB

Mainnet: 46 GB

I haven't updated it again, but it's roughly around those number

  • Mainnet sits currently at 77 gb.

Yes, the disk storage for testnet is vastly smaller than for mainnet.

On my machine the mainnet disk storage is 76 Gig. I would be a little surprised if testnet even uses 10 Gig.

  • Must be more on that testnet than I thought. Aug 18, 2022 at 8:24
