ᐅ Internal dimension of Ikea 20 cm pull-out drawer

Can someone tell me the internal width of the drawers in the 20 cm (8 inch) wide pull-out cabinet? The product description states a total width of 19.6 cm (7.7 inches). However, I’m interested in the actual usable internal width. Unfortunately, I can’t find this information anywhere, and the nearest IKEA is nearly 180 km (112 miles) away, so it’s too far for a quick trip to measure. Thanks in advance for your help. Anita

Another interesting point:
Is it possible to install the two drawers at different heights?
In the picture, it doesn't seem so.
If not, what is the distance between the drawers?

You mean the base cabinet with a height of 80cm (31.5 inches) and a two-tier pull-out, right? The one for bottles and such? If I’m not mistaken, the height of the tiers is fixed.

If that’s the cabinet I’m thinking of, I can measure it for you – I installed it in the fitted kitchen of an apartment, and I’ll be on site on Tuesday preparing for a handover.

Yes, this is exactly the pull-out cabinet I mean. I measured and converted the dimensions from the Ikea pictures.
I arrived at a 10 cm (4 inches) installation space.
But I’m not entirely confident in my research. ;-)
