My main piece of luggage measures 23 x 14 x 9 inches. Will the lockers in the main station in Rotterdam accommodate this?
I am passing through on my way to Amsterdam, and storing here would simply things.
The website for the station
https://www.ns.nl/en/travel-information/luggage/luggage-at-the-station.html
says that the large locker is "90cm deep, 60cm tall and 35cm wide"
In American measurements that is about 35.4 x 23.5 x 13.7 inches.
It likely would fit in the smaller locker which has the same depth and width, and is 45cm tall (about 17.7 inches).
Hubby and I managed to stuff our 2 carry ons and our shoulder bags (barely) into the largest lockers at Rotterdam - you'll be fine.
