The throw line
(also known as the oche, toe-line or hockey) should be about 3 feet wide. It may
be made of tape, a store bought throw-line sticker, a piece of wood or metal. It
should be placed exactly 7 foot 9 and 1/4 inches from the FACE of the board for
a standard steel-tipped setup. For soft-tipped darts, the line should be 8 feet
from the FACE of the board. (NOTE: Some British pubs use an 8 foot or 8 foot 6
inch measurement for steel tip darts.) To measure from the face of the board,
have someone hold a plumb line from the bottom-front of the board to the floor.
If you don't have a plumb line, you can use a piece of string with a pencil or
dart tied to one end. Make sure the throw line is exactly perpendicular to the
face of the board and centered with the board. This can be accomplished by
measuring from the bullseye to each corner of the line.
sservan@ccis.com suggested a great
idea. If you have a carpeted area where you are going to setup your dartboard,
you can use a strip of wood or metal with the "hook" side of a piece of Velco
attatched to the back as your throw line. You can stick it to the carpet when in
use and it won't move, then just rip it up when your done.
