📏 Will SF154 (305×215×37 mm) fit in a letter or parcel locker shipment?

The height of 37 mm makes the box still quite flat, but at the same time it allows to accommodate more items than models up to 20–30 mm. Check how it looks in the context of shipments in various countries:

• 🇵🇱 Polish Post: 37 mm exceeds the registered letter standard (max. 20 mm), but it will work perfectly as an economic package or non-standard shipment (size A/B depending on the total dimensions).
• 📦 InPost Parcel Lockers – Size A: the limit of 640×380×80 mm allows to send SF154 with plenty of room in the smallest locker.
• 🇩🇪 Deutsche Post – Maxibrief: up to 353×250×50 mm – SF154 (305×215×37) meets the requirements, allowing for cheaper letter shipment in Germany.
• 🇳🇱 PostNL: standard brievenbuspakje requires a maximum height of 32 mm, so 37 mm is slightly too much. However, the box can be sent as a package (pakje), while keeping the transport costs low.
• 🇫🇷 La Poste/Colissimo: the size will easily fit in packages and in cooperation with collection points such as Pickup.

As a result, you can easily match Smallfix SF154 to most shipping standards, even when the product requires a bit more space than typically flat letters.
