I know that this question could sound a little bit dumb since Ryanair always sends lot of emails specifying the dimensions of the allowed hand luggage but I am not interested in the "formal" answer but in the "informal" one.

In every airport where Ryanair flies there is a blue box (baggage sizer) where you and the airport staff can put your hand luggage to test if it can be accepted on board. What I would like to know is the dimension of that box (which is of course bigger than the allowed size).

I've been a pretty frequent Ryanair flyer (one flight per month) and I always used the same luggage which was ok for the old box even if bigger than the allowed size.

Few weeks ago Ryanair introduced the possibility to bring a second hand luggage on board. In doing so they also changed the dimensions of the blue box which now has two compartments (one for the main hand luggage, still bigger than the allowed size, and one for the small one). My old luggage doesn't fit anymore in the new boxes so I guess I'll have to buy a new one, hence the need to know how far can I go with the size of the luggage.

Just to understand you better... Your carry on luggage fitted before and now it does not? How is this possible if the new blue box is bigger than the allowed size? In any case... Is this a backpack or something else? – Pixie Feb 18 '14 at 16:36
The blue box has always been bigger than the allowed size (I guess 90% of the carry on luggages I've seen wouldn't pass a strict control). Now it is just "less bigger" than before. – shard Feb 18 '14 at 16:42
Frying in 2 days, if I see the box anywhere, I can try to measure it. – yo' Mar 2 '14 at 1:57
why not use it the way it's meant to be used? check out the maximum allowed size of the bag, then buy one that is just a little smaller than maximum allowed. Then, in case you overstuff it, it will still fit the sizer, as they've allowed a little extra space for people like you. Why push it to the limit? – Peter Perháč Mar 11 '14 at 9:13
@PeterPerháč I get your point but the size allowed by Ryanair is really small. Expecially during winter/autumn, when you really need to bring with you clothes that occupy more space having such a small luggage means you will surely have to board an extra luggage. – shard Mar 11 '14 at 10:25

I measured the box in BSL and it was 21,2 x 41,2 x 58 cm (8.3" x 16.22" x 22.8"). However, the 58 cm are not exact because firstly the box has two rounded rods at the bottom, which makes it slightly smaller at these points, but it's open to the top so this dimension won't matter to much I guess.

I change the accepted answer from mine to yours since you provided the exact measures while I didn't have a meter with me. – shard Jun 9 '14 at 11:55
I took a meter with me only due to this question ;-) – traindriver Jun 9 '14 at 12:12

I had the opportunity to check the measures of the Ryanair "baggage sizer" yesterday even though I hadn't a meter with me. My hand luggage fitted almost perfectly so I can say that the size of the baggage sizer is roughly 23 x 43 x 50 (the last measure is probably the least important one since it is open on top).

In the end, you have something like 3 or 4 centimeters more than the allowed size for each measure.

wow, considering their official dimensions are 20x40x55, that's definitely different enough to matter to some people. – Mark Mayo Mar 24 '14 at 9:03
Height definitly matters. I had to pay excess once for that. They first used the box, where it fited and than they actualy used a meter. It was really bad because it exceeded for 1cm in height and it was an handle. Back then they were beeing very strict. – nsn Jun 9 '14 at 12:48
