Ordered a set of rim-brake wheels recently and they came with the typical quick-releases. It's only when I installed them that I realised that the rear skewer, at the normal road length of 130mm, was a bit short IMO. It wasn't so short that I couldn't apply the quick release but on inspection I considered there wasn't much thread applied.

This made me look at my existing road wheels, from Mavic and Hunt, both appeared to have slightly longer 135mm (mtb length) skewers, which is perhaps why I'd never thought about it before. My rear dropouts don't look that wide. Now I'm looking at a new skewer set, in the meantime I'll use ones from my existing wheels. Any suggestions for good/light skewers?

Good spot.

130mm is the width of a rear road hub so a 130mm skewer isn't much use. Is it possible it's a very old skewer for narrower dropouts? (6-7 speed if I'm not mistaken, do they even use quickreleases, doubt it)

Maybe it's simply a production mistake that slipped past qc checks.

Or like you say, your dropouts are very thick.

Ask 5 people what skewer to buy and you'll get 5 different answers. It's kind of personal. Some prioritize safety above all and wouldn't go below big brand 100gr sets. Some go extreme weightweenie with 2x gr sets.

I'd stay away from carbon and alloy rod ones because of their brittle nature. Titanium or steel rod. 45-55gr ones work pretty ok and clamp pretty well.

For ultrasafe weight weenie seems the lightweight skewers are the kings with steel rods under 50gr. For medium safety, maybe a little flex under sprinting try some titanium rod ones.

Depends a bit on your rear hub as well how much clamping force you need. Some need more, some less.

When road bikes went to disc brakes early on, the standard there was 135mm width on the quick release version. Not sure if you have early QR disc wheels or rim brake.

130mm or 135mm is the width inside the dropouts. The quick release rod needs to be a little more than this to extend past the dropouts. A quick release with a rod length of 130mm would be useless except for on 7s era bikes.

You're right, I meant to describe the dropout width is 130, and not refer that length to that of the skewers; it's just that the skewers are a little short.

It's right in the 5th word of the text! I realise early disc's were that width, I'm on 130 width rim-brake hub.

Never seen a rim rear larger than 130mm only on the disc QR transition. That's my experience. I have however, seen Enve carry both lengths... 130mm and 135mm QR skewer.

This wasn't hugely uncommon when you got the early aluminium frames with thick dropouts compared to the previous generation of nice lightweight steel frames.
The required length of skewer grew about 8-10mm in some cases.

How do you mean "too short" anyway? Where does the end of the threaded shaft come to? And what is the nut made of, some don't need much engagement, others need loads.
