Custom Sewing Patterns vs. Standard Patterns: What Is the Difference?
A standard pattern starts with a size chart. A custom sewing pattern starts with your measurements.
Create My Custom PatternThe biggest difference
Two ways to begin a garment
Standard Pattern
- Starts with a size chartYou choose the closest size from a standard range.
- Graded from a base sizeThe pattern is created for a set of standard measurements.
- Adjustments may be part of the processYou may blend sizes or make fit adjustments before sewing.
Custom Pattern with ALTR HOUSE
- Starts with your measurementsYour measurement profile is part of the pattern's starting point.
- Generated around your profileThe pattern is created from the measurements you enter and the available design details you choose.
- Your body, your styleYou can save your measurements and return to them for future available patterns.
A closer look
What changes when your pattern begins with you?
A standard sewing pattern is designed around a set of body measurements chosen by the pattern company. You select the closest size, then decide whether you want to blend sizes, lengthen or shorten pieces, or make other fit adjustments before sewing.
A custom sewing pattern begins with the measurements you enter. Instead of choosing a standard pattern size as the starting point, you create a pattern around your own measurements first. You can then choose the design details available for that garment.
This does not mean every garment needs no fitting or that fabric behavior never matters. Sewing a test version and paying attention to fabric choice are still valuable parts of a thoughtful make. The difference is that your pattern begins from a more personal starting point.
A more personal starting point
When a custom pattern may make more sense
A custom pattern can be a helpful option when you would rather begin with your own measurements than a standard size chart. It can also be useful when you want to explore available style options without re-entering your measurements each time.
ALTR HOUSE is designed for makers who want a modern digital pattern workflow. You enter your measurements, choose your garment details, then receive a digital pattern in the format that fits the way you sew.
What you receive
Digital files for the way you sew
Your pattern is generated digitally and is available in multiple file formats, including US Letter, A4, A0, and SVG options. You can save your measurements in your Design Studio and use them again when you want to create another available pattern.
The goal is simple: less time starting from a generic size chart, and more time making something that feels personal from the beginning.

Open Live Pattern GeneratorFrequently Asked Questions
Do custom sewing patterns guarantee a perfect fit?
No pattern can account for every fabric, sewing preference, or personal fit preference. A custom pattern starts with the measurements you enter, giving you a more personal starting point than selecting from a standard size chart. A test version is still a useful part of sewing a garment you love.
Do I need pattern-drafting experience to use ALTR HOUSE?
No. ALTR HOUSE is built for makers who are comfortable working with sewing patterns and following instructions. You do not need to draft a pattern from scratch to create a pattern around your measurements.
Can I use my saved measurements again?
Yes. Your measurements are saved in your Design Studio so you can return to them when you want to create another available pattern.
