The two most important resources on any jobsite are money and space. Running out of either can lead to big problems. In this article, we discuss both of these precious resources in relation to conex container sizes for jobsite storage.
Choosing the correct size conex container for jobsite storage is more complicated than it may seem. Smaller units like a 20’ conex container may have a lower rental rate per 4-week period, but delays, inconveniences, and volume constraints can quickly add up. On the other hand, larger units like a 40’ conex container may provide better storage volume value per dollar spent but aren’t always realistic due to jobsite space constraints.
Because of this complexity, we wrote a comprehensive guide to help buyers and renters out. This specific article zooms in on one piece of that puzzle – why conex container size matters more than most people expect. Let’s dive right in!
How Conex Container Size Affects Daily Workflow
On any jobsite, every extra step costs time. When a container is too small, crews end up stacking equipment too tightly, burying frequently used tools, and constantly moving items just to reach what they need. What should be a quick grab turns into five minutes of shifting, digging, and re-stacking. Multiply that by a dozen workers over weeks or months, and the lost productivity becomes real money.
The Benefits and Costs of a 20’ Conex Container
A 20’ conex container often appeals because of its lower rental rate per 4-week period. For smaller projects or tight budgets, that lower cost can feel like the smart move. These units are easier to deliver and place, especially on compact jobsites with limited access or height constraints. Their smaller footprint also means they physically take up less room, which matters when space is already scarce.
On larger jobsites, multiple 20’ containers can be spread around the property, so storage is always nearby. This can reduce walking time and allow different trades to have their own dedicated container. When electricians, plumbers, and finish crews each have their own space, tools stay organized and confusion drops.
The tradeoff is capacity. A 20’ conex container fills much faster than most people expect. Pallets, long materials, and job boxes quickly consume usable floor space. Once it is full, crews start stacking equipment on top of each other or leaving items outside. That leads to wasted time digging for tools, higher risk of damage, and increased exposure to theft. In many cases, running out of room forces the job to add additional conex containers, which erases the original cost savings and increases total spend.
The Benefits and Costs of a 40’ Conex Container
A 40’ conex container provides more than double the usable storage volume of a 20’ unit, especially because of its taller interior height. That extra space allows equipment, materials, and tools to be more spread out instead of piled up. Crews can organize by trade or task, stage materials in advance, and maintain clear separations inside the unit.
Instead of managing multiple small containers, a 40’ conex container allows for one centralized storage area on the jobsite. This often simplifies daily routines and reduces confusion. Workers know exactly where to go. Searching for tools becomes faster and less frustrating. And there is only one lock and key to worry about, not multiple. Although the rental rate per 4-week period is higher, the added capacity delivers more value per dollar spent.
The downside is access. A 40’ conex container is not always possible to deliver, especially on tight sites with limited turning radius or overhead restrictions. Its larger footprint can also block walkways or working areas if the site is not planned for it appropriately, which can introduce its own inefficiencies.
Space and Container Access Limits for Conex Container Sizes
The right choice depends on how space, access, and daily workflow intersect on your site. The goal is not just to store equipment, but to keep people moving and work flowing without friction.
Because of this, conex container size also connects to every other decision on a jobsite:
- Storage containers and office containers feel very different inside.
- Renting versus buying changes how easy it is to fix a mistake.
- Standard sizes can be ordered and delivered faster than custom builds.
- Delivery limits decide what can actually arrive.
- Jobsite layout determines whether size helps or hurts.

Quick Questions About Conex Containers
Is renting two 20’ conex containers the same as renting one 40’?
Not exactly. Two 20’ units give you 40’ of length, but not the same open, centralized space. You also manage two doors, two locks, and two locations.
What access is required for a 40’ conex container?
Delivering a 40’ conex container requires at least 100 feet of straight-line room and a wide turning radius. Tight or obstructed sites may not be able to accommodate it.
Can container size really affect productivity?
Yes. Too-small storage creates daily friction. Crews spend more time searching and re-stacking instead of working.
What’s the most common mistake when choosing a size?
Underestimating space needs. Many start with a 20’ to save money, then add another unit later, which often costs more in the end.
