A seam for a papermakers wet press felt having a flat woven base fabric with the crimped yarns oriented in a lengthwise or machine direction is disclosed. Orientation of the crimp in the machine direction lends itself to an analysis of the crimps per square inch based upon the crimp length and warp end count. Utilizing the crimps per square inch figure, it is possible to establish the approximate minimum length of the join in the machine direction. The minimum machine direction length, in inches, of the join area is approximated by the equation: approximate joined length equals 500 divided by the crimps per square inch in the repeat pattern of the woven base fabric.
