Storage Units Near Me in Marion, TX | Secure Self Storage & RV Parking

Ravali Miryala | February 20, 2026 @ 12:00 AM

Most people who search for a storage unit near them are not actually asking where the nearest facility is. They are asking whether the space they are about to pay for is going to be too small, too big, or about right, and most facility websites answer that question with a generic size chart that could apply anywhere. That chart does not know what you are storing or what this specific facility actually has available.

At Backyard Storage in Marion, TX, the honest answer starts with what is actually on the lot. This facility runs a smaller, more focused unit lineup than a big multi size warehouse, which makes the sizing decision simpler in some ways and more important to get right in others.

At a Glance


  • Backyard Storage offers three storage unit sizes: 10x10 and 10x15 in both economy and standard climate controlled, plus a 10x20 standard unit.
  • A 10x10 unit typically holds the contents of a small one bedroom apartment without furniture stacked to the ceiling.
  • A 10x15 fits a full one bedroom apartment including a couch and bedroom set.
  • A 10x20 is closer to a two bedroom household or a garage full of larger items.
  • Vehicles, trailers, and boats do not go in these units at all. They use the separate parking spaces at the same facility.

Why a Generic Size Chart Does Not Answer Your Question

Most size guides list every unit size a national chain might carry, from a small locker up through a unit large enough to fit a whole house. That is useful if you are comparing facilities city wide. It is not useful once you have already decided you are renting here, because it forces you to translate a generic chart onto a specific, smaller lineup.

Backyard Storage carries three sizes. That is not a limitation stated apologetically. It reflects what this facility is actually built for, which leans heavily toward vehicle, RV, and boat storage alongside a smaller footprint of traditional units. If you searched for a storage unit near you expecting a five size chart with a small locker at the bottom, the honest thing to say is that a unit that small is not part of what is offered here, and that changes the decision from picking a size to deciding whether the smallest available size still makes sense for what you have.

Matching What You Are Storing to What Is Actually Available

The 10x10 Unit

A 10x10 unit is the starting point here, offered in both an economy option and a standard climate controlled option. This size generally works for someone storing the contents of a small apartment without a full furniture set, several rooms worth of boxes, seasonal items, or a single large item like an oversized piece of furniture or a small collection of equipment.

The economy and climate controlled versions are the same footprint with a different environment. If what you are storing is sensitive to heat and humidity, meaning electronics, documents, wood furniture, or anything with fabric or upholstery, the climate controlled 10x10 is worth the difference over a Marion summer. If you are storing tools, patio furniture, or anything that does not mind temperature swings, the economy version covers the same square footage without paying for climate control you do not need.

The 10x15 Unit

Stepping up to a 10x15, also available in economy and climate controlled versions, generally covers a full one bedroom apartment including a couch, bedroom set, dining table, and the boxes that come with an actual move rather than seasonal overflow. This is usually the size someone needs when they are storing an entire household during a transition, not just the extra items that do not fit at home.

The 10x20 Unit

The 10x20, available as a standard unit, is the largest traditional storage size on site. This tends to fit a two bedroom household, a garage full of larger tools and equipment, or a combination of furniture and boxes that would overflow a 10x15. If you are down to choosing between a 10x15 and a 10x20 and you are not sure, the honest rule of thumb is that if your current living space includes a garage or a second bedroom you are clearing out, the larger unit is usually the one that avoids a second trip to upsize later.

What Does Not Fit in Any of These Units

If you are storing a boat, RV, trailer, or an extra vehicle, none of the three unit sizes above are the right category. Backyard Storage handles that need through separate RV, car, and vehicle storage spaces, sized specifically for towing and parking rather than walking boxes through a door. Trying to fit a boat trailer into a 10x20 unit is not a sizing question. It is a different category of storage entirely, and the facility's parking spaces are built for that instead.

When the Smallest Unit Here Is Still More Than You Need

Not everyone needs a 10x10. If you are storing a handful of boxes, seasonal decorations, or the overflow from a single closet, a 10x10 climate controlled unit is going to have more room than you need, and there is no smaller traditional unit at this facility to step down into. In that situation, the honest advice is to look at what you can consolidate, whether a neighbor or family member splitting a unit makes sense, or whether the smallest available size here is still worth it because you expect to add to it over the next few months. A storage decision made for what you have today often needs to account for what you are likely to add within the lease.

Climate Control Changes the Answer, Not Just the Price

Choosing between economy and climate controlled at the same size is not purely a budget question. Marion summers run hot enough that a standard unit's interior temperature can climb well past outdoor air temperature over several months, and materials like wood, leather, paper, and electronics degrade faster under sustained heat and humidity swings than most people expect. The climate controlled storage option at both the 10x10 and 10x15 sizes exists specifically for that reason, not as an upsell on an otherwise identical unit.

If what you are storing would be fine in a hot garage for a summer, economy covers the same square footage for less. If it would not survive a hot garage, the size decision and the climate decision are really the same decision.

Renting the Right Size the First Time

Getting the size right before move in day matters more than it sounds, since moving between unit sizes after the fact means an actual second move, not just a phone call. If you are between two sizes, the safer choice is usually the larger one, especially if anything you are storing might grow over the lease term, whether that is a move that is not fully finalized yet or a garage cleanout that tends to turn up more than expected once you start.

For anyone comparing a traditional unit against drive up access instead, the drive up storage page covers how loading and unloading differs by access type, which matters as much as square footage if you expect to be in and out of the unit often. And if the choice actually comes down to climate control versus drive up convenience rather than size, the comparison of drive up and climate controlled storage walks through that tradeoff directly.

Backyard Storage is located at 885 FM78 East in Marion, TX, and current availability for all three sizes can be checked directly through the facility page before you commit to a size based on a chart alone.
