How do I Know What Mailer Size to Buy?

When it comes to protecting your products, choosing the right mailer size is key.

Too small and you risk damaging the mailer or your product. Too large and you’ll reduce protection and pay more in shipping costs. It’s a decision that requires some thought, for sure.

So, how do you know what mailer size to buy? Let MailerShop.ca help with that.

Measure your product

You need to know the dimensions of the item you’re mailing. Use a ruler or measuring tape to measure its length, width, and height. Round those numbers up to the nearest inch to ensure you’ll choose a mailer that’ll fit your product comfortably.

Consider your shipping options

What shipping method are you using?

If you’re shipping internationally or being charged by dim weight, you’ll want to choose a mailer that’s as small as possible (without sacrificing protection, of course) to keep the weight down and save on shipping costs.

What are the shipping regulations?

This is mostly relevant if you’re shipping something unusual or to a remote location. But it’s still a good idea to check postal regulations for your product type and shipping options. Some postal services have specific size and weight restrictions for different types of mail.

Choose a slightly larger mailer

You need some breathing space to accommodate both the product and its padding, but you don’t want to go too large and lose protection. This is where those rounded numbers come into play. Choose a mailer that’s about an inch bigger in length and width.
