Longest desktop instruments (in a home lab)?

Dang, some of you guys have pretty long.... *ahem*.

Anyway, a while ago I bought a standard 90 cm deep laminated kitchen fiberboard and mounted it on top of a custom metal frame that I'm now using as my current workbench space. It was placed against a wall, and the space was plentiful, but then I decided to add some shelving. Having 40 cm shelves with 5 cm spare space in the back for cabling gives me another 45 cm of free work space, which I figured isn't a lot. Using shelves any longer than that will give me even less workspace, so I have a bit of a dilemma here. Since I'm already stuck at 90 cm, I think I'll go for 40 cm shelves. I would have bought a larger board, but 90 cm were the deepest laminated kitchen particle boards that I could find (it's a standard dimension here in EU).

I originally planned to have instruments on the first shelf at eye-level, but it seemed a bit too low and didn't leave much vertical space underneath. But then I've seen some people design their workbenches in a way where two shelves of different lengths are used (see pic below). The bottom shelf is very short and is used for shorter instruments like scopes - it rest slightly below the eye level and leaves plenty of available workspace in front. The next shelf is at eye-level or slightly above, and hosts deeper instruments like PSU's, DC loads, etc.

Most people who receive a -hp-3456A moan about the depth of the meter.  It's 20.75" (527.1mm) deep, so most modern instruments will be less methinks.

My shelving is setup so the lowest shelf above the bench is 30cm, so it does not get in the way of the bench, the shelves above that are 40cm.

Yeah, my HP 8570A is 570mm deep, and you should always factor in some space behind for routing cables and a bit of ventilation.

The other thing with modern instruments is they are a lot lighter, so you don't need a massively reinforced bench to carry a full basic set (ie scope, SA, sig gen, DMM, LCR, PSU, load, and not forgetting you need multiples of each, really...)

Discerning followers of my behind-the-scenes "test and measurement fundamentals" Instragram may notice that my entire "bench" is one single 29x29 inch (72x72 cm) wooden table.  Seriously :)  I've never had an instrument that was too long to fit safely on my table (and I have probably had literally 100 different instruments on that table), so I would second the recommendation of 80 cm.
