I reckon this is what you want:

-------------------------------------------------
import Tkinter

root        = Tkinter.Tk()
canvas      = Tkinter.Canvas(root)
canvas.pack()
text        = canvas.create_text(100,100,text="Hello World!")
x0,y0,x1,y1 = canvas.bbox(text) ## The coords of the bounding box
rect        = canvas.create_rectangle(x0,y0,x1,y1) ## To demonstrate
textwidth   = x1-x0 ## The width of the text in pixels
print textwidth ## To demonstrate
root.mainloop()
-------------------------------------------------
