27" x 1 1/4 tires are roughly 630mm ISO BSD; 700C tires (the most common road tires now) are 622mm. There is enough room on most common 700C fenders to adjust for the 7mm difference without any problems.
That being the case, 1 1/4 inches is roughly 32mm so I would go up a size to 45mm fenders if you have the clearance for maximum coverage. Get full fenders that mount properly, they work much better than partial fenders.
EDIT: SKS fenders are great, Planet Bike Freddy Fenders are well regarded, and my bike shop has some other cheaper plastic fenders that fit 700C
