There are many different types of Near Field Communication (NFC) chips on the market, each of which contains a different amount of user memory. There are two versions of NXP Semiconductors' MiFare Classic chip, for example. One features 1 kilobyte of electrically erasable programmable read-only memory (EEPROM), while the other offers 4 kilobytes of memory. I would say that 1 kilobyte is common.
