What Size Box Do I Need? A Practical Guide for Shipping & Storage

Choosing the wrong box size is one of the most common packaging mistakes businesses make. A box that’s too large increases shipping costs and damage risk, while a box that’s too small can crush products or cause delays.

This guide explains how to choose the right box size for shipping, storage, and moving—so your products stay protected and your costs stay under control.

Why Box Size Matters More Than You Think

Using the correct box size helps you:

• Reduce shipping and courier costs

• Prevent product movement and breakage

• Avoid overusing void fill

• Stack boxes safely on pallets

• Improve customer satisfaction

For businesses shipping across Saskatchewan and Alberta, box size matters even more due to long distances and stacking during transport.

Step 1 – Measure Your Product Correctly

Before choosing a box, measure your product in three dimensions:

• Length

• Width

• Height

Always measure at the widest points, including packaging like bubble wrap or foam.

Rule of thumb: Add 1–2 inches of extra space on each side for cushioning.

Step 2 – Understand Standard Box Sizes

Most corrugated boxes come in standard sizes designed for common products.

Typical uses:

• Small boxes → books, cosmetics, electronics

• Medium boxes → apparel, home goods

• Large boxes → bulk items, light but bulky products

If your product doesn’t fit standard sizes, custom box sizing reduces waste and improves protection.

Step 3 – Choose the Right Box Strength

Box size alone isn’t enough—you must match strength to weight.

• Single-wall boxes → light to medium products

• Double-wall boxes → heavy, fragile, or stacked shipments

A large box with weak walls will fail under pressure.

Step 4 – Consider Shipping Distance & Conditions

For local shipping or pickup:

• Standard box sizes usually work well

For long-distance shipping across Alberta or Saskatchewan:

• Choose stronger walls

• Avoid oversized boxes

• Ensure proper internal support

Long transit times and stacking increase stress on boxes.

Common Box Size Mistakes to Avoid

• Choosing the largest box “just in case”

• Ignoring product weight

• Using weak boxes for stacked shipments

• Overusing void fill instead of proper sizing

These mistakes increase damage, returns, and shipping costs.

When to Use Custom Box Sizes

Custom boxes are ideal when:

• Products don’t fit standard dimensions

• You ship the same product repeatedly

• You want cleaner stacking and branding

• You want to reduce packaging waste

Many Prairie businesses save money long-term by switching to custom sizes.
