<p>I applied to Stanford SCEA, and they made it clear that they wanted teacher recommendations in the large 9x12 envelopes so they weren't folded. I haven't found these stipulations on any other college site, and I was wondering whether any of the following colleges also have weird envelope size requirements.</p>
<p>Harvard
Princeton
Yale
MIT
Caltech
Duke
UPenn
Harvey Mudd
Rice</p>
<p>Thank you</p>
