Shed Calculator

  • It is assumed that the shed has an internal nail sill all around, The sil is usually a metal tube or a wood board that allows attaching the shed to the surface.
  • Place anchors per shed's manufacturer instructions.
  • If manufacturer instructions are not available, follow the steps below:
    • Place one anchor 1' from each corner except on door wall IF there is no sill under the door.
    • On the door wall without sil, place one anchor midway on each side of the door.
    • Add anchors between the corner anchors so that no two anchors are spaced more than 6' apart.
Planning estimate only. This calculator uses the assumptions in this form and current product data; unusual installations or high-risk conditions should be reviewed by a qualified professional.
