For purely educational purposes (wink wink) what is the theoretical maximum number of characters I can have in a custom string property on a perspective component?

I've seen the limit for [memory tags](https://forum.inductiveautomation.com/t/memory-string-tag-and-text-area-maximum-number-of-characters-size-of-string/46750), does that same limit apply to custom properties on perspective components?

I imagine it would be that limit minus all the characters taken for the actual view configuration.

Java strings can be ~4GB. Somewhat less than that, I would presume.

you're putting string encoded view json into custom properties in your UDTs, aren't you? 😉

Long before you hit Java or JS string size limits, you'll bump into limitations syncing property messages:

> **[Perspective Parameters | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.1/appendix/reference-pages/gateway-configuration-file-reference/perspective-parameters#web-socket-message-size)**
>
> Gateway Configuration

Marking properties as private will help with this (as we will no longer unnecessarily sync `custom` properties to the frontend), but I'd still expect you to start getting issues with things like saving your project in a timely manner and general slowdown/weirdness as you give us a way bigger value than we're "expecting" _way_ before you hit the max length of a string.

I wouldn't put more than a few thousand characters into a Perspective property, and even then I'd question my design assumptions and be actively planning a different solution.
