Storage Unit Sizes in Seguin, TX: Which Unit Do You Need?

725 Self Storage
September 28th, 2026

Picking a storage unit size is the one decision most people get wrong the first time. Too small and the last load of boxes ends up back in the garage. Too big and every month costs more than it should. 725 Self Storage in Seguin, TX offers four unit sizes, 10x10, 10x12, 10x15, and 10x20, and this guide walks through what actually fits in each one so the first pick is the right pick.

The Four Unit Sizes at 725 Self Storage

725 Self Storage offers temperature-controlled units, and every unit sits inside a fenced, gated property with keypad entry and video cameras throughout. Rates run from $115 to $140 per month depending on size, and new move-ins get the first month free with a six-month stay. Current pricing and availability are always listed on the rates page.

10x10 (100 square feet)

About the size of a half garage. A 10x10 holds the contents of a one-bedroom apartment: a queen mattress and box spring, a dresser, a couch, a small dining set, and 20 to 30 boxes. It is the most common pick for Texas Lutheran University students storing a dorm room between semesters, or for a couple moving into Seguin who need to park furniture for a month or two while a closing goes through.

10x12 (120 square feet)

The extra two feet of depth make a real difference. A 10x12 handles a one-bedroom apartment plus the overflow that never fits: patio furniture, a bike or two, seasonal decorations, or a set of golf clubs. It is also a comfortable size for a small business keeping inventory, tools, or records off the shop floor.

10x15 (150 square feet)

Roughly a two-bedroom apartment or a small house. Expect room for two bedroom sets, living room furniture, appliances like a washer and dryer, and 40 or more boxes. Families relocating to Seguin from San Antonio or New Braunfels often land here, since it holds most of a household while a home is being finished or renovated.

10x20 (200 square feet)

The size of a standard single-car garage. A 10x20 fits a three-bedroom house: multiple bedroom sets, dining and living room furniture, appliances, and the boxes to go with them, with walking room down the middle. Contractors and businesses working around Guadalupe County use this size for equipment and bulk stock as well.

How to Estimate Before You Rent

A quick way to size a unit: walk through each room and count the large pieces (beds, couches, tables, appliances), then count boxes. One bedroom of furniture plus 15 to 20 boxes is about 50 square feet. Add 50 square feet for each additional furnished room. If the count lands between two sizes, go up. Stacking to the ceiling works for boxes, but furniture needs floor space, and a unit packed wall to wall is hard to get into when one item is needed in the middle of the month.The size guide on the 725 Self Storage website has a visual reference for each unit.

Why Temperature Control Matters in Seguin

Seguin summers regularly push past 100 degrees, and an uninsulated metal unit can run 20 to 30 degrees hotter than the air outside. That heat warps wood furniture, cracks leather, fades fabric, and ruins electronics and photographs. 725 Self Storage offers temperature-controlled units, so clothing, furniture, artwork, documents, and anything else that does not belong in a hot garage is stored at a steady temperature year-round. For long-term storage in Central Texas, that is the difference between getting items back in the condition they went in and replacing them.
