"15.6-inch laptop backpack" is not the size of the sleeve: it is the class of laptops the sleeve was designed for. Internal sleeve dimensions are not published on Piquadro product pages, so no page can guarantee that a specific computer fits. This guide explains what the declared diagonal means, why 15 and 15.6 inches are two different values in the catalogue, and proposes eight backpacks available online grouped by declared diagonal, with the sheet data you need to compare them.

What the declared diagonal does and does not say
The Piquadro technical sheet carries, for every backpack, a "laptop compartment size" attribute with values such as 13.3, 14, 15, 15.6, 17.3 inches. The value is the screen diagonal of the laptop class the sleeve is sized for. Three practical consequences:
- 15 and 15.6 are different sleeves: both values exist in the catalogue and they are not interchangeable. A sleeve declared for 15 inches is not declared for 15.6; a 15.6 sleeve is not declared for 16.
- The diagonal is not a measurement of the sleeve: two 15.6-inch laptops can differ in width and thickness, and the internal sleeve dimensions are not published. The product page is the source to check for your own model.
- Sleeve position: the sheet declares whether the sleeve is external (dedicated pocket, quick access) or internal (inside the main compartment). Useful if you go through airport security often.

When to choose another model
- If your laptop is 16 inches: none of the models in this guide declares it. Do not use a 15.6 sleeve by inference: compare your computer's size with the product page or choose a sleeve declared for 17.3.
- If your laptop is 15 inches: the catalogue has bags with a sleeve declared for 15 inches; look for them among the laptop bags reading the sheet attribute, not the title.
- If you use a case: the added thickness is not covered by the declared diagonal. Check with the case fitted.
- If you carry a 13-inch laptop: laptop backpacks with a sleeve declared for 13.3 inches can be filtered in the collection.
Frequently asked questions
Will my MacBook, ThinkPad or Surface fit?
The sheet declares only the diagonal; it publishes neither the internal sleeve dimensions nor a list of tested models. Compare your computer's size with the product page or try it in store. We do not infer compatibilities that are not declared.
Why do some titles say 15 and the sheet 14, or the other way round?
The reference figure is the "laptop compartment size" attribute of the technical sheet, which feeds the site filters. Where title and sheet differ, the sheet applies; let customer service know.
External or internal sleeve: what changes?
External means a dedicated pocket with its own zip, useful to take the laptop out without opening the main compartment. Internal means inside the main compartment. For all eight models listed the sheet declares shock-absorbing protection for the sleeve.
Conclusion
Start from your laptop's diagonal and choose only among the models that declare it: 14, 15.6 or 17.3 inches. Then compare net weight, capacity and sleeve position. Certain compatibility with a specific model requires a physical test: internal dimensions are not published.
