Frequently asked questions
What size is a Jiffy bag size 4?
225 x 343mm (8.75 x 13.5in).
Is it a Large Letter?
Yes, provided the packed bag is no thicker than 25mm and no heavier than 750g.
Will A4 fit?
Not flat: A4 is 210 x 297mm and the bag is 225mm wide, so it fits only with very little padding room. Size 5 is the safer A4 choice.
