Book Shipping: The maths behind large letter tariffs

Book Shipping: The maths behind large letter tariffs

Do you want to mail your books in the most economical way with as little thought at possible?

Do you find yourself having to go through the maths every time you want to send a book in the post, or just not worry, and suffer the expense of creeping into the next price band? If you are only sending out the odd package, this is probably not too problematic, however, when mailing out on a larger scale, this would be time consuming and possibly very costly.

Many countries operate volumetric cost assessments. Large letter is a tariff used for small packages that don't exceed 35.3cm in length and 25cm in width. The maximum thickness allowed in the large letter category is 2.5cm, and with a weight limit of up to and including 750g. The cost of sending out a package in this category is £2.46 to send the item 1st class with Royal Mail and £2.09 for 2nd class delivery. Too much information here comes a little more

If your package doesn't free fall through the large letter slot, it will be classed as a parcel. Once into the next category of small parcel, the price leaps up to £3.35 to send the package 1st class and £2.85 for 2nd class delivery.

There are penalties in operation for incorrect postage payments which can be charged to the recipient of the package. You don't want your customer to be on the wrong end of a fine plus the discrepancy in the postage fee.

Ensuring that your package fits into the large letter bracket, can therefore involve a whole lot of measuring, squashing and calculating as mentioned in our 'book packaging guide'.
