Most people either underestimate how much they own or overestimate how efficiently they'll pack. The result is a unit stuffed to the ceiling with no room to access anything — or a half-empty unit they're overpaying for every month.
Win Win Storage in Newton Grove offers 15 different indoor climate-controlled unit sizes, from a 5×5 up to a 10×30. That's the widest selection of any facility in Sampson or Johnston County — which means you're far more likely to find an exact fit rather than being forced into the next standard size up. Use this guide to pick right the first time.
These four sizes cover single-room storage, seasonal overflow, and compact personal use cases.
5×5 (25 sq ft) — Think large walk-in closet. Right for seasonal decorations, boxes of documents or keepsakes, small furniture like end tables and lamps, or sporting equipment (fishing gear, hunting supplies, camping gear). Not the right choice if you need regular access or have anything larger than a bookshelf to store.
5×10 (50 sq ft) — One full bedroom's worth of furniture plus boxes. Common uses: a bed frame and dresser, contents of a studio apartment, motorcycle storage, or business records. Good for single-room moves and short-term transitions.
5×13 (65 sq ft) — A step up from the 5×10 in depth. Fits a single bedroom plus an extra row of boxes or a few additional pieces. Useful when the 5×10 feels like a tight squeeze but you don't need a full medium unit.
7×10 (70 sq ft) — Slightly wider than a standard 5-foot unit, which matters if you're storing wider items like a loveseat, a workbench, or equipment that won't fit through a 5-foot opening. Good option for a small home office setup, a motorcycle plus gear, or tools and seasonal outdoor equipment.
This range handles most residential storage situations. The standard jumps between 10×10 and 10×15 are well-known — the in-between sizes (10×12, 10×13, 12×13) give you options to avoid overpaying when you're right on the edge.
10×10 (100 sq ft) — The most popular size at most storage facilities. Holds a two-bedroom apartment's worth of furniture, a full living room plus bedroom set, or one car's worth of garage contents (tools, lawn equipment, boxes, shelving). A solid starting point for most residential storage needs.
One note for rural households in Sampson and Johnston County: a 10×10 that fits a two-bedroom Raleigh apartment can feel tight for a three-bedroom farmhouse in Newton Grove. Farmhouses accumulate more — tools, seasonal outdoor gear, furniture passed down across generations. When in doubt, size up.
10×12 (120 sq ft) — Between a 10×10 and 10×15. If a 10×10 is just slightly undersized for your needs, the 10×12 lets you get the extra space without jumping to a full 10×15. Good for a two-bedroom home with a few extra pieces or a small business with modest inventory.
10×13 (130 sq ft) — Similar story. Practical for 2–3 bedroom household contents when a 10×10 is too tight but you don't yet need a full 10×15.
10×15 (150 sq ft) — The step up for full home storage. Fits a 2–3 bedroom home including living room, dining room, and bedroom furniture plus major appliances (washer, dryer, refrigerator). Also handles farm and shop equipment alongside household goods. Good for full home storage during a renovation, military PCS, or downsizing from a larger home.
12×13 (156 sq ft) — Similar square footage to the 10×15 but wider. The extra two feet of width makes a difference if you're storing wide items — an oversized sofa, a riding mower, commercial shelving — that won't easily fit into a 10-foot-wide space.
These six sizes handle full households, commercial inventory, contractor staging, and estate storage.
10×17 (170 sq ft) — A useful step between the medium range and a full 10×20. Good for a 3-bedroom home's contents without the full garage, or a medium business inventory situation.
10×20 (200 sq ft) — Roughly the size of a standard one-car garage. Holds the contents of a full 3–4 bedroom home, significant commercial inventory or contractor equipment, multiple appliances plus furniture, or a small car or truck. A common choice for contractors along the I-40 corridor who need a secure staging area for tools and materials between jobs.
12×19 (228 sq ft) — Wider than a 10×20 with slightly less depth. Useful when you need the square footage of a large unit but have wide items (large farm equipment, oversized furniture, commercial fixtures) that benefit from extra width.
10×25 (250 sq ft) — Extra depth for long items or for customers who want a center aisle to access their unit regularly without digging. Fits everything a 10×20 holds with room for a sectional, long lumber, or a workspace inside the unit.
13×20 (260 sq ft) — The widest indoor unit we offer. The extra width is the key feature — three feet wider than a standard 10-foot unit means items that won't slide through a normal corridor can be accommodated. Oversized furniture (king suites, antique armoires, large sectionals), wide commercial equipment, or estate cleanouts where everything needs to go into a single unit.
10×30 (300 sq ft) — Our largest unit at 300 square feet, equivalent to a large two-car garage. Built for high-volume situations: full multi-room household storage, large commercial inventory, contractor operations requiring dedicated staging space, or estate storage involving contents from an entire property. If volume is the primary concern, this is the unit.
Most storage facilities offer a small set of standard sizes — 5×5, 5×10, 10×10, 10×15, 10×20. If your needs fall between those jumps, you're either cramped or overpaying.
With 15 sizes available, Win Win Storage is more likely to have a unit that actually fits your situation. The difference between a 10×12 and a 10×15 is about 30 square feet — and if you only need the 10×12, there's no reason to pay for the larger unit every month.
National storage size guides are calibrated for urban and suburban apartments. Rural households in Sampson and Johnston County are different:
A good rule of thumb: if you live in a house rather than an apartment, start one size tier higher than the standard guides suggest and work down from there.
Every unit at Win Win Storage is climate-controlled — you don't have to choose between size and protection. We maintain temperatures between 60–80°F year-round and use six industrial dehumidifiers to keep relative humidity at or below 50%.
Eastern North Carolina summers regularly push outdoor humidity above 70–80%. Items most at risk in uncontrolled storage:
If you're comparing Win Win to an outdoor facility in Dunn, Clinton, or elsewhere in the area — climate control is the defining difference, not just a feature.
What is the most popular storage unit size?
The 10×10 is most commonly rented. It holds a two-bedroom apartment's worth of furniture or a full one-car garage.
What fits in a 5×5 storage unit?
A 5×5 is similar to a large walk-in closet — seasonal decorations, boxes, small furniture, or sporting equipment.
What is the largest storage unit at Win Win Storage?
Our largest unit is 10×30 (300 sq ft) — equivalent to a large two-car garage. We also offer a 13×20 for customers who need extra width for oversized items.

15 different climate-controlled sizes, from 5×5 up to 10×30 — the widest selection in Sampson or Johnston County.

Yes. Every unit at our Newton Grove facility is climate-controlled, with temperatures held between 60–80°F and humidity at 50% or below.
How do I know if I need a 10×10 or 10×15?
A 10×10 works for a two-bedroom apartment or a full one-car garage. Step up to a 10×15 if you're adding major appliances, a full living and dining room set, or farm and shop equipment.
