What’s the ideal pad size for writing on airplanes? A good friend, and fountain pen aficionado, swears by the 5 x 5 size. His usual 8 1/2 x 11 is too big to fit when the tray is lowered.
The 6 x 8 1/4 works best on tray-size for me; although if I use my preferred No. 18 (8 1/4 x 11 3/4), I compromise by using my bag as a lap desk.
What size is your ideal traveling pad?
