Hoop Widths

The rules for what widths hoops should be set to are not entirely easy to comprehend. Hopefully the tables below will summarise the information.

Non-Tournament Settings

The 'generic', non-tournament, setting for general croquet is given as the internal width between the hoop uprights (the gape). It should lie between 3 ¾ inches and 4 inches.

3.b HOOPS

  1. SPECIFICATION Each hoop is made of solid metal and consists of two uprights connected by a crown. A hoop must be 12 inches in height above the ground measured to the top of the crown and must be vertical and firmly fixed. The uprights and the crown must have a uniform diameter of 5/8 inch above the ground although minor deviations at the top and bottom are permitted. The inner surfaces of the uprights must be approximately parallel and not less than 3 ¾ inches or more than 4 inches apart (subject to Law 53(b) for tournament and match play). Each hoop on a court must have the same dimensions within a tolerance of 1/32 inch. The crown must be straight and at right angles to the uprights.

Further digging in the Laws book (Appendix 1) reveals these measurements have a tolerance of +/- 1/32"

Tournament Settings

These settings come from the UK Tournament Regulations (2016). Other countries may have different regulations and hence permitted dimensions.

Regulations for Tournaments 2016
APPENDIX 1 - Hoop Setting, Ball Specification and Inspection Requirements

  • HOOP WIDTH. The clearance is defined as the difference between the distance between the inside edges of the uprights at half-ball height and the maximum diameter of the largest ball to be used on the court. Unless otherwise advertised in the Calendar, or as stated below, hoops must be set such that the clearance is as near as possible to:
  • 1/32" for Championship events (see C2(b)(3))
  • 1/16" for events played under conditions of Advanced Play and events played under mixed conditions
  • 1/8" for handicap and other events

Tolerances on hoop settings are +0% and -50% in each case. The Manager may, in accordance with Regulation M2.C.10, alter the advertised clearance by up to 50% in either direction, provided that this and the reason for it is publicised before play starts that day.
