How to Create a Sloper with KATAPATA
From Measurements to PDF Export

KATAPATA guides you step by step from entering measurements to reviewing, adjusting, saving, and exporting your sloper as a PDF. This article explains the basic workflow for first-time users.

Before you begin

KATAPATA is a browser-based tool for creating sewing slopers. It can be used on smartphones and tablets, but a larger PC screen is recommended when you want to review the overall shape or make fine adjustments.

prepare measurements such as bust, waist, and back length
use a browser that can save PDF files
decide where you want to store your working data

If you are not sure where to measure, check the Measurement Guide before you start.

1. Enter your measurements

Open the sloper tool and enter your body measurements. Use your actual body measurements rather than the measurements of a finished garment.

Keep the unit consistent. Do not mix centimeters and inches. If a value is far outside the expected range, review the on-screen message and check the number again.

2. Create the sloper

After entering the required measurements, follow the on-screen steps to create the sloper. The exact parts and workflow differ slightly between the Women’s and Men’s Sloper Tools.

STEP 01 Enter measurements Input the measurements you have taken.

STEP 02 Generate the sloper KATAPATA calculates the basic sloper from your values.

STEP 03 Review and adjust Check the overall shape and refine the areas you need.

The first generated shape is based on your measurements and the basic drafting calculation. Posture, shoulder slope, and other features that measurements cannot fully describe can be reviewed in the adjustment step.

3. Adjust the sloper on screen

Use the adjustment points on the sloper to refine areas such as the shoulder, neckline, armhole, bust point, and sleeve cap. You do not need to move every point—adjust only the areas that need attention.

Switch between overall and individual views

First review the bodice and sleeve together, then switch to an individual view when you want to see a specific part at a larger size.

Small adjustments are easier to judge. Move a point a little at a time and review the whole shape before making another change. Undo and Redo are also available when needed.

4. Save your data

You can save your working sloper as KATAPATA data and reopen it later to continue editing.

use a file name that makes the purpose or date easy to recognize
keep the original data and save adjusted versions separately when useful
back up important data in another location

When continuing on the same device and browser, you can also use the browser-resume option. The working data and the finished PDF serve different purposes, so it is useful to keep both if you may want to adjust the sloper later.

5. Export and print the PDF

When you are satisfied with the sloper, move to PDF export. Depending on your purpose, you can choose from full-size PDF, tiled A4 PDF, tiled US Letter PDF, and a reduced-size sample PDF.

Full-size PDF

Use this when printing on a large-format printer or through a printing service where the full sloper can be handled as one large page.

Tiled A4 / US Letter PDF

Use these formats when printing on a home printer. The sloper is divided across multiple pages that you can print and assemble.

Print at 100% scale. Options such as “Fit to page,” “Scale to fit,” or automatic shrinking may change the size of the sloper. Choose “Actual size,” “100%,” or an equivalent setting, and check the printed reference scale first.
