Online shopping continues to grow, and with it the number of parcel deliveries to homes. Many households face the same problem: a delivery arrives when nobody is home, after which the parcel ends up at a collection point, with a neighbour, or scheduled for a second delivery attempt. A parcel mailbox helps prevent this, but only when the size is chosen correctly. A model that is too small only solves part of the problem, while a model that is too large is not always necessary for every home. In this guide, you will learn which dimensions are practical, which capacity suits your use, and which models are suitable for single-person households, families, frequent online shoppers, and small businesses.
The ideal size for a parcel mailbox depends on the type of parcels you usually receive. As a minimum, a parcel opening suitable for parcels of around 13 × 33 × 22 cm is practical for smaller online orders, accessories, books, personal care products, and compact webshop deliveries. For average families, a model that can handle parcels up to around 29.5 × 16 × 37.5 cm is often more useful. This gives more margin for shoe boxes, clothing parcels, and several smaller deliveries on the same day. For frequent online shoppers or families that often receive larger boxes, a parcel mailbox with capacity up to around 43 × 22.5 × 22 cm is the strongest choice. It offers more flexibility for deliveries when nobody is present.
Small parcel mailboxes are suitable for households that receive a parcel from time to time. They take up little space, fit well in narrow front gardens or compact facade areas, and are usually sufficient for small webshop deliveries.
Medium parcel mailboxes are the most balanced choice for many homes. They combine manageable external dimensions with enough internal capacity for regular parcel deliveries.
Large parcel mailboxes are designed for frequent online shoppers, larger families, and homes where several parcels are delivered each week. They offer more capacity and reduce the chance that a delivery will not fit in the mailbox.
The Practo Garden Dortmund parcel mailbox with rear retrieval in matte black is an excellent choice for anyone with limited space who mainly receives compact deliveries. Thanks to its modest dimensions, the mailbox remains discreet, while its capacity is more than sufficient for daily small parcels.
The Practo Garden Hannover parcel mailbox in matte black offers the same compact parcel capacity in a clean design. This model is suitable for anyone looking for a simple solution for regular deliveries without installing a large parcel mailbox.
The eSafe Dropbox Small Parcel Mailbox Black is the best choice when you order online regularly and want more flexibility without immediately choosing a large model. The larger parcel opening makes this model suitable for a wider range of everyday deliveries.
| Model | Max parcel | Suitable for | Capacity |
|---|---|---|---|
| Practo Garden Dortmund | 13 × 33 × 22 cm | Compact use | Small |
| Practo Garden Hannover | 13 × 33 × 22 cm | Regular small parcels | Small |
| eSafe Dropbox Small | 29.5 × 16 × 37.5 cm | Regular online orders | Medium |
Single-person households usually receive fewer parcels at the same time. A compact parcel mailbox is often sufficient, especially when orders mainly consist of small accessories, books, personal care products, or documents.
However, avoid choosing a model that is too small. Even with limited use, a slightly roomier model can be useful when you occasionally order shoes or clothing.
Families benefit more from a medium or large parcel mailbox. Several household members often order from different webshops, which means deliveries are more likely to arrive on the same day.
For families, capacity is more important than appearance alone. A model that can handle parcels up to 43 × 22.5 × 22 cm offers more certainty for clothing, toys, school supplies, and household products.
Anyone who orders online every week should not choose the smallest size. A larger parcel mailbox helps prevent deliveries from still being missed.
Pay particular attention to the maximum parcel size, not only the external dimensions. A model may look large but still have a limited insertion opening.
Small businesses that regularly receive parts, samples, documents, or stock mainly need reliability. A medium to large model is usually the best choice.
Placement is especially important: the delivery driver must be able to recognise the parcel mailbox quickly and use it safely. For home offices or small practice spaces, this can prevent many missed deliveries.
Choose the material based on appearance, maintenance, and placement. A black steel parcel mailbox fits well with modern facades and driveways, while corten steel is especially suitable for gardens, rural-style homes, and outdoor areas where a warm, robust look is desired.
Also consider the surroundings when choosing the material. If the parcel mailbox is fully exposed outdoors, a well-finished model is more important than when it is placed under a roof or in a sheltered entrance area.
Always check the maximum parcel size, not only the total external dimensions. The outside may look spacious, while the effective opening determines which parcels can actually be received.
For occasional small parcels, 13 × 33 × 22 cm is often sufficient. For families or regular online orders, extra margin is more practical, especially when several deliveries may arrive on the same day.
A parcel mailbox is often placed in a front garden, near a driveway, against a facade, or by an entrance gate. Rain, wind, and visibility therefore play a role in choosing the size and location.
Make sure the delivery driver can see the mailbox quickly and use the opening easily. A location that is too hidden or difficult to access increases the chance that parcels still end up at a collection point or with a neighbour.
That depends on the model. Compact models can, for example, receive parcels up to 13 × 33 × 22 cm, while larger models can handle parcels up to 43 × 22.5 × 22 cm. Always check the maximum parcel size, not only the total external dimensions.
Bigger is not always better. A large parcel mailbox offers more capacity, but it also requires more space near the facade, front garden, or driveway. The best choice is the size that matches your delivery frequency and available space.
A shoe box only fits if the maximum parcel size of the mailbox is large enough. Compact models may be tight, while medium and large models are more likely to receive shoe boxes without problems. Always check the dimensions of the parcel opening.
For an occasional small order, a compact parcel mailbox is often sufficient. For families or frequent online shoppers, a medium or large model is the better choice. Anyone who receives several deliveries per week should choose extra margin instead of the minimum size.
