Theoretically infinite given an adequate power supply. The bottleneck would eventually be the data packet size for very large arrays vs the desired refresh rate. I think the WS2812b only has a refresh rate of 400Hz, so you'd probably max out pretty quick for large scrolling text displays. Using something like the WS2813, with a 2000Hz refresh rate, would be better for a large display. But to answer your question, you'd have to calculate the baud rate for n LEDs, then see if that results in an overall refresh rate of 26hz or higher (lower than that the movement starts to look choppy).
Thats a great project. Can it be scaled up to make a display say 3 times bigger? will your code support a bigger display would like to try foe a festive display
The speed and data baud rate might be a problem, also you will likely need to remap all the LED's. There's only one data channel and it has to loop around all strands. This one by Josh Levine only has 7 strips in parallel but is nearly limitless with proper power inputs every so often. You have 2000 characters for a message as the message is stored in S-RAM. ruclips.net/video/k-SYMPO8-f8/видео.html

The only small problem with these strips for making such display is the joint where two led strips is joined by manufacture. These joint normally misaligned the entrie matrix. For this de-soldering and re doing is required in order to align the same

Thats a great project. Can it be scaled up to make a display say 3 times bigger? will your code support a bigger display would like to try foe a festive display
The speed and data baud rate might be a problem, also you will likely need to remap all the LED's. There's only one data channel and it has to loop around all strands. This one by Josh Levine only has 7 strips in parallel but is nearly limitless with proper power inputs every so often. You have 2000 characters for a message as the message is stored in S-RAM. ruclips.net/video/k-SYMPO8-f8/видео.html
