I am planning on making this bread soon. The only thing that has me stumped is the loaf pan size. The original recipe yields a pretty big loaf and  calls for a 13x33x12cm pan which converts to 5x12x4 inch loaf pan?? Anybody who's made this bread please let me know if this is correct.

I want to half the recipe, so the right size pan would be 2.5 x 6 x 2 inch pan. The problem is I don't own such a pan and I have never seen such being sold in any store. So what pan should I use to bake?

Original recipe is http://schneiderchen.de/237Hokkaido-Milky-Loaf.html [1]
