It depends on which LP release you have and how many layers of inner liner there are. That said, our sleeves are large enough for most double LPs if you have the original jacket.
The fit would be pretty snug around double or gatefold album covers. With a single "regular" LP there should be a little room left in the sleeve.
Triple LPs are often packaged as a collector’s box set and have inner liners that add to the thickness, so we do not recommend one sleeve for these.
