What is exactly one and a half meters?

It's roughly one Roel van Velzen, as he joked on social media, and if you find that difficult, then it's 15 HEMA cream puffs. But one and a half meters turns out to be a tricky and abstract concept for people. I just had someone cycling right through my one and a half meters. That makes me a bit angry. How hard can it be? We'll visualize it for you.

To start with: an ironing board, a hockey stick, a vacuum cleaner handle, a Billy bookcase, and even your trash can all have one thing in common: they come up a few centimeters short in the one and a half meter space. So what does fit?

 One and a half meters is six lying wine bottles.
So a box, but laid out horizontally. Cheers.

It's easier than it seems. Just stretch your arms wide when passing someone and the other does the same.

One and a half meters is the width of a piano.
So play that scale loudly when someone gets too close.

One and a half meters is a folded bicycle.
Or as they say in Belgium: a folding bike, which sounds much friendlier.

One and a half meters is your desk.
That standardized thing we've all sat at at some point.

One and a half meters is just not quite the width of a Fiat 500.

One and a half meters is a metal detector.
Not that you can picture that, but our Annick insisted that I mention it.

One and a half meters is a child of about eleven years old.
Not one with growth spurts or taller than average, but with a child of that age, you could measure it just fine. Just lay it down.
