* There are countless objects of that size. A ruler, a smartphone, a small book, a piece of paper, a banana – all of these could be 11 centimeters long.
* "Long" is relative. What seems long to one person might seem short to another.
To help me guess, tell me:
* What category is the object in? (e.g., kitchen utensil, electronic device, toy)
* What is the object used for?
With more information, I might be able to narrow down the possibilities!
