A mailer box can make all of the difference in the world! If it’s too small, your products will break, and if it’s too big, you’ll end up paying for space you don’t need. Use the right size so your products remain safe, look good, and are easy to ship.

Whether you run an online store selling apparel, make skincare products, or deliver gifts, knowing the right size of mailer box is vital to making your customers happy. Here are some common sizes, materials, and some tips to choose the right one for you.

Why Do Businesses Use Mailer Boxes?

Mailer boxes are useful, strong, and easy to assemble. They fold to keep items secure during delivery, and some even close without additional tape.

Online retailers, beauty brands, subscription businesses, and gift shops use these boxes to store everything from small accessories to folded clothing.

Another benefit of mailboxes for businesses is the space to add their logo, company colours, and printed messages. The right package will make an ordinary delivery feel personal, and will encourage customers to remember your brand.

What Are the Standard Mailer Box Sizes?

Mailer boxes come in different sizes, and the right option depends on what you’re sending. Although there isn’t one universal standard for every UK supplier, the following dimensions are useful starting points.

These are example sizes, so always check the dimensions available from your packaging supplier before ordering.

An ideal size box can fit a necklace or a few beauty products, whereas a larger box may be better for several items. Think about what’s in the box, not just what’s inside it.

How Do You Measure a Mailer Box Correctly?

The right measurements from the start can save time and money. First, measure the length, width, and height of your product. If you’re packing something delicate or oddly shaped, measure its widest points.

Think about how much room you’ll need for tissue, inserts or other protective items. You don’t want the boxes to be too full, but too much room can cause items to slide around in the box on delivery day.

Also, know the difference between internal and external dimensions. Internal dimensions tell you how much room is inside the box. External measurements help you determine whether a parcel has a maximum size limit and how many parcels will need to be shipped.

Before buying hundreds of boxes, try a sample box. If one is available, put your product in, close the lid, and check that everything fits snugly. It’s a small step that saves you from costly errors down the line.

Which Mailer Box Material Should You Choose?

The material matter as much as the size. After all, a perfectly sized box will do little good if it’s not strong enough for your product!

Corrugated Cardboard Mailer Boxes

Corrugated cardboard is an popular choice for shipping because of its fluted middle layer, which provides added strength and cushioning. It’s a great choice for many online orders, product bundles, and items that need extra protection.

The weight of the item and how it will be delivered determines the strength of the board.

Kraft Mailer Boxes

Kraft mailer boxes have a natural look that is ideal for clothing brands, handmade goods, and small businesses. They can also be printed with logos and other branding elements.

Many options of kraft packaging can be recycled, depending on the materials, coatings, adhesives, and recycling facilities in your area.

Printed Paperboard Boxes

The paperboard box is a good option if presentation is important. They are versatile and can be printed with colours, patterns and brand messages for an attractive look. The board must be suitable for the weight of the product and the way it will be transported.

Why Are Custom Mailer Boxes Worth Considering?

Occasionally standard sizes are just not enough. You may be sending an organized set of skincare or several items in one package. In this case, a custom mailer box may be the better option.

You can choose sizes to fit your products and a style to match your brand. Choose a tighter fit to eliminate unnecessary space, and inserts that will help the contents stay put.

Another perk to print it yourself is that you can add your logo, colours, or even a quick thank-you note, and create a more thoughtful package without making it too intricate.

Businesses considering whether to purchase printed packaging boxes should compare the box size, quality, printing, and order quantity before making their decision.

How Do I Choose the Right Mailer Box Size?

Yes, selecting the right size can help you control shipping costs. Some carriers calculate prices using both the weight of the package and its volumetric weight, which indicates how much space the parcel occupies.

For example, if you send a light product in a large box, it will likely cost more than sending it in a smaller, properly-fitted box.

To cut costs, use a box appropriate to your package and the packaging material it may contain. Ask your courier if they have size restrictions. Do not include packaging that has no function.

Despite this, don’t make the box too small to save money. Always place the product first.

What To Check Before You Place a Bulk Order?

Prefer not to order a large number of mailer boxes? Read on.

• Size: Check the internal dimensions fit your product.
• Intuition: Pick a material that offers sufficient protection.
• Check your logo and colours are right for printing.
• Price: Compare the cost of all products, including printing and set-up costs.
• Delivery: Confirm the expected production and delivery times.
• Samples: Test a box before making a large purchase.

Also, consider the space required for storage. Getting more boxes might lower the cost per unit, but you’ll want somewhere to store them until they’re used up.

Final Thoughts

The best mailer box isn’t the largest or cheapest. The right one will fit your product, protect it while it’s being shipped, and present your business well.

Start by measuring your items, leave room for packaging materials, and compare sizes prior to making any changes. It will save you from unnecessary packaging, shipping costs, and damaged orders.

By choosing the right size, material, and design, your mailer boxes will make it easier for you to deliver on time and leave your customers with a positive first impression of your company.
