This is likely to vary from one phone to another. However, as a guideline, you should aim to keep compiled pages under 1,400 bytes.

The limitation is for the nokia 7110. This phone is understood to have the lowest deck size, 1397 bytes.

1WML file = a deck

A deck can contain one set of head information and multiple cards.

Deck size is calculated by the total number of bytes in a compiled deck. note: each tag gets compiled into one byte as does each letter of text and block of white space. The Nokia toolkit will display a deck size when you are looking at a compiled page.

Different browsers and phones have different deck sizes.
Below is a sample of what the are.

UP.Browser 3.2  1492 bytes  
UP.Browser 4.x  2048 bytes  
Ericsson R320  Aprox 3000 bytes  
Ericsson R380  Aprox 3500 bytes  
Ericsson MC218  More than 8000 bytes  
Nokia 7110  1397 bytes  

But when you are developing a page to be displayed on a mobile device, you should try and keep the deck size as small as possible. The reason for this is that standard GSM networds only have a 9.6kb bandwidth so it takes a few second to download a page that is larger that 1000kb. A user might think there phone has crashed/hung or experienced another problem and might try to reconnect. So if it is suitable you should try to have decks of around 600 kb.
