Can I bring a book in my carry-on bag?

The answer is yes, without any restrictions. A book is a solid, non-sharp object that does not fall under any of the categories of items subject to carry-on luggage limitations. You can take as many books as you like in your carry-on bag, provided that your entire luggage complies with the dimensions and weight authorized by your airline. No European or international airport regulations restrict the transport of books in carry-on luggage.

This total freedom regarding books in the cabin is often misunderstood by travelers who sometimes confuse restrictions on liquids and sharp objects with more general restrictions on the contents of carry-on bags. Airport regulations for carry-on luggage are actually much more targeted than many travelers think. They mainly concern liquids, gels, and pastes subject to the 100 ml rule, sharp objects and weapons, and certain hazardous materials. Books, magazines, notebooks, and all paper documents are completely exempt from these.

The only practical consideration to keep in mind when taking books in carry-on luggage concerns their weight. A standard book weighs between 300 and 500 grams, and several books can quickly add up to a kilo or two towards the total weight of your luggage. On airlines that impose a strict weight limit on carry-on bags, such as low-cost carriers that often limit cabin bags to 7 or 10 kilograms, every kilo dedicated to books is one kilo less available for your clothing and personal effects.

In this article, we provide you with all the practical advice for traveling optimally with your favorite books in carry-on luggage without unnecessarily weighing down your bag or compromising your travel comfort.

How many books can you take in carry-on luggage?

There is no regulatory limit on the number of books you can take in your carry-on bag. The only constraint that applies is the total weight of your luggage, which must comply with the limit imposed by your airline. It is therefore a matter of managing available weight rather than a question of airport regulations.

To calculate how many books you can reasonably take without exceeding your carry-on luggage weight limit, it is useful to know the average weight of a book according to its format. A paperback novel generally weighs between 150 and 250 grams. A large-format novel or self-help book weighs between 300 and 500 grams. A beautiful illustrated book or technical manual can weigh between 800 grams and 1.5 kilograms. These benchmarks allow you to quickly estimate the weight your reading selection represents before adding it to your luggage.

On a low-cost airline that limits carry-on luggage to 7 kilograms, taking three to four paperbacks represents about 800 grams to one kilogram, which is a reasonable portion of your available weight quota. On the other hand, taking two large illustrated books represents 1.5 to 3 kilograms, which significantly reduces the space available for your clothes and personal items.

The e-reader is the most effective solution for frequent readers who do not want to compromise their luggage weight with physical books. A Kindle or Kobo e-reader weighs between 170 and 250 grams and has a storage capacity for thousands of books. For a traveler who reads two or three books a week during their vacation, an e-reader represents a considerable weight saving compared to the equivalent in paper books. It also has the advantage of ensuring you never finish your last book in the middle of a trip without having the next one on hand.

If you are set on paper books and the weight of your carry-on bag is a serious constraint, a strategy commonly adopted by travelers is to leave the book at your destination once finished, at your accommodation or in a local book exchange box, rather than bringing it back in your return luggage.

Do books need to be removed from luggage at the security checkpoint?

This question is worth asking because the answer has evolved in recent years and varies depending on the airport and the security procedures in force. The general rule applied in the majority of European airports is that books do not need to be systematically removed from your bag at the security checkpoint, unlike liquids, laptops, and large electronic devices. However, some airports and some security officers may ask you to remove them in specific situations.

The reason why books can sometimes cause issues at security is their density on the scanner. A thick book or a stack of several books in a bag can create an opaque mass that is difficult to read correctly on an X-ray scanner, as the density of the paper absorbs the rays and makes objects located behind the books less visible to security officers. This opacity on the scanner can lead an officer to request a manual search of your bag to verify its contents or ask you to take your books out to be screened separately.

In American airports in particular, the Transportation Security Administration has for several years recommended that travelers remove their books from their bags and place them separately in a bin during the security screening to facilitate scanner inspection. This recommendation is not a legal requirement, but it is often applied de facto by officers who may interrupt the flow of luggage to manually inspect any bag containing a mass of paper that is difficult to analyze on the scanner.

The best practice to avoid any delay at the security checkpoint is to group your books in a pouch or easily accessible compartment of your carry-on bag. If an officer asks you to take them out, you can do so quickly without having to rummage through your entire bag. This preventive organization is particularly useful in high-traffic airports where the fluidity of the security checkpoint is a priority for agents and where any slowdown is quickly flagged.

In practice, the vast majority of travelers who take one or two books in their carry-on luggage encounter no complications at European security checkpoints. Situations that generate requests to remove books are primarily those where several thick books create a significant mass that is difficult to analyze by scanner, or where other items in the bag have already triggered an alert that requires a full manual inspection.
