spreader length.

[VicS]

Would it be true to say that with a conventional rig of cap shrouds plus two pairs of lowers that the spreader length, tip to tip, will be the same as the horizontal separation of the shroud anchor points, making the bottom section of the cap shrouds ( spreader to deck ) vertical

Thanks . Between 75% and 100% of the horizontal separation of the anchor points is an adequate answer for my purposes.
