Sizing Page: This is a high volume armory set up with the intentions of serving such groups as the SCA which our founder is a long time member. We do not do custom sizing per se. We do, however, have several stock sizes that are orderable with several drop down menus for sizing. So in a way, all of our orders are custom sized, determined by the customer's choices. Since we use mostly metric sizing, a customer has advised us of this handy site where people can get conversions from or to standard measurements. http://www.onlineconversion.com/length_common.htm WE DO take returns (see our info page for specs), but it is better to check sizing than pay for non-refundable shipping charges to get a product exchanged.
