That was a fascinating question, so I spent some time looking it up. I wanted to know the diameter of the LMC because I already knew the diameter of our own galaxy, and could therefore get the relative size. In doing so I discovered that Wikipedia already answered the question.

From a hypothetical planet in the LMC, the Milky Way would be a spectacular sight. The galaxy's total apparent magnitude would be -2.0—over 14 times brighter than the LMC appears to us on Earth—and it would span about 36° across the sky, which is the width of over 70 full moons. Furthermore, because of the LMC's high galactic latitude, an observer there would get an oblique view of the entire galaxy, free from the interference of interstellar dust that makes studying in the Milky Way's plane difficult from Earth.[10] The SMC would be about magnitude 0.6, substantially brighter than the LMC appears to us.
Oh, another page puts the Milky Way at 20 times the diameter of the LMC.
