Quality of images exported as JPEGS from Lightroom

AnimalRights

I never really went into my export settings referring file size and my Jpegs always ended up around 5mb, I just noticed the wedding pics I exported are all around 1mb so I went into file settings in export and seen it was on about 60% quality and I know for a fact I def didn't change it.
I did a test where I moved the slider up to 100% quality and exported a duplicate pic and it was now 7mb, so I looked at the 2 files side by side on large size and cannot actually tell the difference at all.
I am due to put the 115 pics onto a disc my question is shall I export all again to my standard 5mb size or is there actually any diff if I just use the 1mb size?
Camera is 5D III btw.

Still seems a bit small ?

My Quality on LR4 is set to 9 or so and after exporting from RAW most JPEGS are 20-30 MB ... also 5D III

That seems very large for a jpeg, I'd expect a tiff to be in that range...

My files in Raw format are 25mb or so...and I just double checked teh camera that is normal Raw not sRaw.

i don't have LR here, but a 12MP RAW file from my nikon D300 (15.5MB file), just exported from camera RAW at a quality of 10 (out of a max. of 12), works out at 4.06MB.

on a computer screen, files will look same (or should) - the differences will only be seen if printed to a large size - so best to give them largest file poss i.e. the 7mb files

Really excellent analysis here : http://regex.info/blog/lightroom-goodies/jpeg-quality

Level 8 roughly = 10 in photoshop and should pretty much always be all you need.

Ya I exported all again in 90% quality

While we are on the subject of lightroom exporting, what should the image sizing setting be set to, as regards to W: and H:?

Depends on what you want.

Some, I want to export at max size, some I want to restrict size for web or facebook or such.

It all depends on your needs.

If you're only printing A4 or 8x10, then a file size of 1mb is more than fine.

Only if you don't zoom in at all. There is a reason Lightroom has that handy one-click-zoom feature.
