Have no ideaā¦ I am so horrible at mental picture sizing lol They are aluminum so I donāt think itāll be too difficult to trim them up if needed
They measure out to 4" high x 17" wide (10.16cm x 43.18cm) and are the smallest they makeā¦hopefully theyāll fit your tardis - if not, signage for around it like you mentioned before or send them back and iāll think of something else
