Hi there! We're very sorry to hear that your cover size was too short to cover one side of your mailbox.
We offer two size options of mailbox covers that fit most mailboxes on the market. It sounds like our larger size option may have been a more suitable option in this case. We always encourage our customers to measure their mailbox for accuracy before placing their order with us.
In some rare instances customers may need a cover size that we don't showcase on our site, but you can always reach out and we can customize to any size dimensions you may need.
We sincerly value and appreciate your feedback and we'll make sure to look for ways to review and improve our sizing options with better clarity.
Thank you
