Pocket construction

Create an in-seam pocket pattern

Generate a hidden pocket bag for skirts, dresses, pants, or shorts. Choose compact, standard, or deep proportions, use separate bag pieces or a folded one-piece construction, and export the result at full scale.

Check before cutting

Place the opening marks on the garment side seam and test hand access, bag depth, seam finishing, and show-through before cutting final fabric.

In-seam pocket bag

Generated example

A usable pocket bag drafted from dimensions

Live geometry

The preview uses the same geometry engine as the downloads and includes the attachment edge, opening notches, grainline, cutting line, and seam allowance.

Opening

16 cm pocket entrance

The marked attachment edge gives a clear start and end point for the side-seam opening.

Bag

17 × 27 cm standard bag

The rounded standard preset gives practical hand room and carrying depth without excessive bulk.

Dimensions remain full size through SVG, copyshop PDF, and tiled A4 export, with a 5 × 5 cm scale-check square.

Generated in-seam pocket bag

Choose separate pieces for a conventional construction or a connected folded bag to reduce the outer bag seam.

In-seam pocket guide

A hidden pocket bag sized for the side seam

The generator turns the required pocket opening and bag dimensions into a print-ready pattern piece. Use these notes to place the opening and select a construction that suits the garment and fabric.

Included

Opening marks, grainline, seam and cutting lines

Every export includes the pocket-bag outline, start and end notches for the opening, grainline, selected seam allowance, cutting instructions, and a 5 × 5 cm test square.

Opening

Match the entrance to the wearer and garment

Measure a comfortable hand opening and confirm its position on the garment side seam. The opening should sit below the waist treatment without colliding with a zipper, waistband, or hip shaping.

Depth

Choose practical carrying room

Bag width controls hand room away from the seam, while bag depth controls how far the pocket extends downward. The generator protects a minimum depth below the opening.

Construction

Separate bags or one folded piece

Separate construction uses two bag pieces per pocket and is familiar to sew. Folded construction joins both halves at a fold, reducing one seam but requiring a larger fabric area.

Fabric

Control bulk and show-through

Use stable lightweight pocketing where possible. Check opacity, stretch, seam finishing, and whether the bag needs anchoring to a waist seam in soft or loose garments.

Printing

SVG, copyshop PDF, or tiled A4

Print at actual size or 100%, disable page fitting, and measure the test square before assembling pages or cutting fabric.

Who, how, and when

Drafting logic by Nastix Design

This generator is maintained as application code: measurements are converted into vector geometry, related seams are measured numerically where the construction requires it, and the same geometry is used for preview, SVG, copyshop PDF, and tiled A4 PDF.

Generator content and output workflow reviewed 13 July 2026. A generated block remains a fitting starting point; verify measurements, print scale, fabric behaviour, and a test garment.

Common questions

In-seam pocket pattern FAQ

Is the in-seam pocket generator free?

Yes. Enter the dimensions, preview the generated bag, and download SVG, copyshop PDF, or tiled A4 PDF.

How long should the pocket opening be?

It should comfortably admit the wearer’s hand. Test the opening on the actual garment and consider seam allowance, waistband position, and any closure.

What is the difference between separate and folded construction?

Separate construction uses two bag pieces for each pocket. Folded construction connects both halves at a fold, removing the outer joining seam but using a taller fabric piece.

Which pocket-bag shape should I choose?

Rounded bags distribute contents smoothly and are easy to finish. Straight bags use clearer corners and can suit structured or utility garments.

How should I print the A4 pocket pattern?

Print at actual size or 100%, disable fit-to-page scaling, and confirm the test square measures exactly 5 × 5 cm.
