Şalvar Pattern Generator

Enter your measurements in inches and the generator draws your cutting diagram to scale, with every dimension marked. The wedges you cut away become the gores — nothing is wasted. How to take each measurement and the sewing order are in my Turkish pants class handout.

Measurements

Waist around where the pants will sit — used to check the finished width Rise measured as

Rise sit on a hard chair; measure side waist straight down to the seat Crotch ease added to the rise so you can sit and move Length waist to ankle, bent forward, measured down the back of your leg — keeps them from riding up when you sit Around the foot around your heel with toes pointed, tape pulled snug — sets an ankle your foot fits through without slipping off Fabric width optional — for the layout and yardage below

Pattern dimensions

A	Panel width, on the fold
B	Diagonal cut
C	Panel length
D	Ankle width, on the fold
T	Drop from waist to diagonal
G	Gore at its widest
E	Gore-to-gore seam

Rounded to the nearest ⅛″. Six pieces per pair: two leg panels, each cut on a lengthwise fold, plus the four gore wedges the diagonal cuts free. T is one-third of your rise plus ease; G, the gore at its widest, is the other two-thirds — together they make the full crotch depth. Panel width A follows from the ankle plus the gore.

Cutting diagram — one leg, on the fold

Cutting the folded panel goes through both layers, so each leg frees two wedges — those four wedges are your gores, six pieces in all. Flip each wedge wide end up and sew it back diagonal edge to diagonal edge, one on each side of the leg, then join the pants front and back along the gore-to-gore seams.

Sewn view — one leg, gores in place

Each shaded gore is a wedge from the cutting diagram, flipped so that diagonal sews to diagonal along the dashed line. Its widest edge (G) lands at the start of the cut, T below the waist, and the wedge's straight side swings outward to become the free edge. Folding the leg into a tube brings the two straight edges together — that seam is E, which is simply C minus T.

Construction

Stitch both gores to each pant leg as shown in the sewn view, lining up the widest part of each gore with the start of the diagonal cut, below the waist. The gore will not completely meet the hem at the ankle.
Stitch the gores together along seam E (), creating a tube for each leg.
Turn one leg inside out, and insert one leg inside the other, right sides together.
Line up the crotch and the front and back seams, and stitch the pant legs together, matching up gores and seams.
Remove the one pant leg from inside the other, and turn the garment right side out.
Create a casing at the top edge, and finish the ankle seams.
Insert a drawstring or elastic (or both), as desired, into the waist casing.

Elastic isn't period, but alongside a drawstring it keeps full pants up off wet or dirty privy floors.
