How to Choose the Right Size for Your Needs

While knowing what can fit into each unit size is helpful, the key to choosing the right unit comes down to understanding your specific needs. Here are a few things to consider when deciding on storage unit size:

  1. Inventory Your Items
    Take a look at everything you need to store and make a list. If you're storing furniture, consider the dimensions of each item. For boxes, estimate how many you’ll need and their size. You can even stack items in your home to get an idea of how much space you'll need.
  2. Consider Future Growth
    Will you need to add more items in the future? If so, it might be worth renting a slightly larger unit now to avoid having to upgrade later.
  3. Access Frequency
    If you plan to access your storage unit frequently, choose one that’s easy to get to and has enough space for you to move around comfortably. A 5x10 unit may be a great choice for someone storing a few boxes and not needing to access them often.
  4. Budget
    Naturally, the larger the storage unit, the more it will cost. Be mindful of your budget and try to choose the smallest unit that will meet your needs without cramping your storage space.
  5. Climate Sensitivity
    If you're storing valuable items like artwork, electronics, or antique furniture, consider renting a climate-controlled unit. These units maintain a stable temperature and humidity level, which will help preserve the condition of your belongings.

Originally known as Decoration Day, Memorial Day began after the Civil War as a time for Americans to honor fallen soldiers by decorating their graves with flowers, flags, and heartfelt remembrance. Today, it continues as a powerful tradition of gratitude and patriotism. Across the nation, communities come together for parades, ceremonies, and moments of silence—united in honoring the courage and commitment of those who died in service to the United States. As we gather this Memorial Day, we pause to reflect on the true meaning of the holiday—not just as the unofficial start of summer, but as a solemn and patriotic tribute to the brave men and women who made the ultimate sacrifice for our country. At the heart of Memorial Day is a deep appreciation for the freedoms we enjoy—and for those who protect them. Standing with Our Military—Past, Present, and Future We are proud Americans, and we stand firmly with our military community. We value and appreciate the dedication and sacrifice of those who wear the uniform—often leaving behind their spouses, children, family, friends, and loved ones to serve with honor and pride. With family currently active in the military, our appreciation is personal. We understand the challenges that come with military life—the frequent moves, deployments, long-distance separations, and constant uncertainty. It takes resilience, strength, and commitment—not just from the service members themselves, but from their entire families. That’s why we’re proud to be a supporter of those who currently serve and those who have served this great nation. Storage Solutions That Serve Those Who Serve From basic training to deployment and every transition in between, military life often means packing up and relocating—sometimes with short notice. We know that when duty calls, the last thing you need to worry about is where to keep your belongings. With convenient locations in multiple states, we’re proud to offer flexible, secure self storage solutions that make life a little easier. Whether you're moving across the country, downsizing for a deployment, or simply need extra space while on assignment, we’re here to help with: Clean, secure units in a range of sizes Easy month-to-month leases Affordable rates Exclusive military discounts A team that understands and respects the military lifestyle We’re honored to serve those who serve—and to be a trusted resource during life’s many transitions. This Memorial Day, We Remember. We Honor. We Serve. As flags fly high and families come together to celebrate the spirit of freedom, we remember the fallen heroes who made this day possible. Their courage lives on in every salute, every folded flag, and every grateful heart. Whether you’re enjoying a backyard barbecue, heading to the lake, camping under the stars, hitting the beach, catching a cruise, traveling for vacation, or simply relaxing at home—take a moment to remember why we’re free to do all of it. Wherever you are, and whatever you’re doing with the people you love, we hope your Memorial Day is filled with gratitude, reflection, and pride.
