A reminder why SegWit is an “actual” blocksize limit increase; and why those saying otherwise are unfortunately spreading misinformation

Segwit

Client Maximum blocksize the client can see
Upgraded clients 2MB (or more*)
Non upgraded clients 1MB

   

”Simple” hardfork to 2MB

Client Maximum blocksize the client can see
Upgraded clients 2MB
Non upgraded clients 1MB

   

Note: * An additional piece of misinformation going around is that because SegWit allows blocks larger than 2MB, this extra data must be spam, and therefore SegWit allows 4MB of spam data and only 2MB of “real” transaction data. This is also false. SegWit allows for a theoretical maximum of 4MB of transaction data, of course the 4MB COULD include spam data, but any data in any part of the block COULD be spam. The 4MB could also be “real” transaction data
