Check how much space a single row takes in Sqlite

Question

Is there a way to check how much space a single row takes in Sqlite?

I have tried using this way:

I have 4 fields in my table:

id(int)
name(text)
pat(text)
is_default(bool) 

select *, sum(length(name)+length(name)+length(pat)+length(is_default)) 
from color;

But it returns character length (for example: 43). How can I determine the row length in bytes?
