How many moving boxes do I need?

Understanding moving box types and sizes.

First, it's important to understand the different types of moving box sizes.

Extra small boxes (15 x 12 x 10 inches), ideal for:

• Tools
• Books
• Collectibles

Small boxes (16 x 12 x 12 inches), ideal for:

• Books
• Glasses
• Dishes
• Small appliances
• Collectibles
• Magazines
• DVDs
• Canned food

Medium boxes (18 x 18 x 15 inches; 22 x 16 x 15 inches; or 3 cubic feet), ideal for most household items, including:

• Office supplies
• Photo albums
• Home decor
• Small appliances
• Toys
• Records

Large boxes (18 x 18 x 24 inches; or 4.5 cubic feet), ideal for bulky items, like: 

• Pillows
• Comforters
• Linens
• Large dishes
• Board games
• Vases

Extra-large boxes (22 x 22 x 21.5 inches), ideal for bulky items like: 

• Blankets
• Towels
• Pillows

There are also specialty packing boxes, such as: 

• Wardrobe boxes for hanging clothes
• Dish barrel boxes with cell dividers to separate individual dishes and glasses. These boxes typically have a heavy-duty design to protect fragile items.
• TV boxes for flat-screen TVs of varying sizes
• Mirror and picture boxes, which you can also use for art pieces
• Book boxes, which are made specifically for small yet heavy books

Calculate how many moving boxes you really need.

The Home Depot has a handy moving box calculator that helps you understand how many boxes you might need based on your space. Follow these steps: 

1. Select what type of space you're moving out of.
2. Select how many bedrooms you're moving.
3. Enter how many mattresses you're moving. 
4. Select which additional rooms you're moving (if any).
5. Enter how many TVs or art pieces you're transporting.

You will get a list of the moving materials you need. You'll also receive an estimate of how many boxes of each size you should get. 

Here are three examples the calculator gave me:

Example A: Moving items out of 1 bedroom and a kitchen from a house with 0 mattresses and 1 80" TV.

• 1 heavy-duty TV moving box
• 1 small moving box with handles
• 7 heavy-duty small moving boxes with handles

The Home Depot isn't the only one that has a moving box calculator. Check out these online resources as well:

• CNET's moving box calculator will help you find the number of boxes you might need based on square footage. 
• Moving.com's packing and moving box calculator to see how many boxes you and other supplies you should get, including markers and bubble wrap.
• U-Haul's moving supplies calculator also gives recommendations for packing supplies, like tape and packing paper. 

Still not sure how many boxes you need? Ask a pro.

If you already plan to hire professionals to help you with your move, ask them to estimate how many boxes you might need. 

Many moving services offer packing supplies. You may need to pay a fee, or they may offer them as a complementary add-on. Some movers may also allow you to use their boxes for free as long as you return them within a specific time frame.
