Smart Locker Sizing for Residential Buildings

Smart Parcel Lockers are growing in popularity, especially in residential buildings where there is an unprecedented increase in parcel volume due to the growth in online shopping, fueled by COVID-19. For those thinking of getting a parcel locker, one of the key questions is what size locker do I need? 

First and foremost, what is the volume of parcels you receive on a daily basis? Ideally, If you have a way to track this over an extended period of time (2 to 3 months), you can determine, with confidence, what your average daily volumes are. Couple this with the expectation that this number will likely increase by 10 to 20% in the coming year and you now have the data to determine the size of locker you’ll need to adequately handle your volumes.  

If you don’t have the time, resources, or staff to record how many shipments you’re receiving on a daily basis the average daily parcel volume can be estimated by using a factor of five or six and dividing it into the number of units in your building. For example, if you have a 300 unit building you can estimate that you’re receiving between 50 and 60 parcels per day. 

Once you know your daily parcel volume, you then need to work out the locker size that will adequately handle this. This is driven by your parcel storage policy. In other words, how many days will parcels be allowed to be stored in the locker before they’re removed? For most residential buildings this is 48 hours to 72 hours (2 to 3 days). If you implement a 2 day expiry policy you will need a locker with 30% more slots than your average daily volume and 50% for a 3 day policy. So, if your daily volume is 50 parcels and you want to have a 2 day expiry policy you’ll need a locker with 65 slots. 

The next thing you need to consider is the number of each slot size you need. Generally, a small parcel slot in a Smart Locker will measure 4 or 5 inches high by 16 inches wide and 24 inches deep. Medium, large and extra large slots will measure about 9, 16, and 25 inches high respectively (all with the same width and depth as the small slot). Some lockers have even larger slots but many property managers prefer to limit the larger sizes in lieu of having more of the smaller sized slots. Parcels being delivered into residential buildings come in a variety of shapes and sizes but the general distribution of parcels will fit into a locker that has 43% small, 43% medium, and 16% large and extra-large slots.

Most Smart Parcel Lockers are about 24 inches deep and 78 inches high. For every 20 inches of locker length, you can expect to have, on average, 8 locker slots. With the calculated number of slots you need you can now figure out how much space you’ll need to house your locker. Using the numbers above, if you need 80 slots you can figure that you’ll require about 200 inches (or about 16 feet) of linear space.  

We mentioned earlier that the growth of parcel volumes will likely be between 10 to 20 % per annum for several years to come. Smart Lockers are readily expandable but ideally, you will need to find a space that will give you expansion capabilities for the future. Keep in mind that these lockers don't have to be in a straight line as they can be positioned in an L or a U shape or they can be back to back. They can also be separated but the distance between the sections should be in close proximity so the user can easily find the slot with their parcel in it when they go to retrieve it.
