Yep. Bow length is measured nock to nock along the back of the unstrung bow, following the contour of the limbs. That's why an unstrung recurve may be 58 inches tip to tip, but 60 inches between the nocks when measured along the back. Most longbows will have 1/2 to 3/4 inch sticking out beyond each nock groove so their total length will be a little longer, i.e., a 64-inch longbow, will come in at about 65 1/2 overall. Strung, it will probably be closer to 63 inches tip to tip because the tips are pulled closer together when strung.
