Hi Audrey,
Thanks for your feedback.
I've checked your order carefully, the size you ordered is an 11x14" poster.
If you received the wrong size, please take a photo with the measurement tape on the poster.
In case we sent the wrong size to you, we will replace a new one for you as soon as possible.
Please send the photo to our support email support@batenstore.com, we will examine it carefully and solve it within 24hours.
Thank you so much!
Customer Support Team.
