Make sure you will still have enough space either side of the strings to stay on the neck as it will put the outer strings closer to the edges and of course widen the space between each string.
Check carefully if the saddles will actually fit as they may well not, depending on the bridge.
Might be a mistake. I tried to replace saddles on a Pacifica and the replacement ones I got were slightly wider than the stock ones... as you might guess, 5 saddles would fit but the 6th would not. I got a second set of replacement saddles in a smaller size, still wouldn't fit the 6th saddle. From that experience I'd wager that direct replacements are going to be a better bet. It's amazing what a few millimeters can do to throw off the entire instrument.
why not just get properly sized saddles?
No kidding, it's an extra .30 or .36 mm across the span depending on the math.
Actually, it's about 3mm wider overall, nearly 1/3 the width of a 10.2mm saddle. What guitar/bridge are these saddles going on?
10.3 mm here, but pricey like a whole new bridge

those are chrome plated brass saddles
yeah, that should be fine.
solspirit Just a heads up for everyone here. I make my own brass saddles (Killer Guitar Components). If any of you need a set or a special size or a combination of materials (I make aluminum as well) or whatever - drop me a line. I'd be happy to help.
I'm going to have to take you up on that if it's not too expensive. I think solid brass with no chrome might different than chromed brass and solid is what I was originally looking for.
Shoot me a DM and I'll give you the dimensions and we can talk price.
