What Is a Low Shank Sewing Machine?
When exploring the world of sewing machines, you’ll often hear the term “low shank.” Understanding what a low shank sewing machine is can make your sewing experience smoother, especially if you enjoy using different presser feet and accessories. In simple terms, a low shank sewing machine refers to the design and height of the presser bar—the part where the presser foot attaches. The “shank” specifically refers to the metal rod that holds the presser foot in place.
To determine if your machine is low shank, pay attention to the distance from the bottom of the presser foot holder to the screw that attaches the presser foot. On a low shank machine, this distance is typically around 3/4 inch (about 0.75 inches or 19mm).
Understanding this key detail is important for several reasons:
- It dictates which presser feet and attachments you can use.
- It helps you identify compatible accessories when shopping.
- It enables smoother transitions between sewing machine components.
Now, let’s break down everything you need to know about low shank sewing machines, how to identify them, their pros and cons, and some handy tips to get the most out of your sewing machine.
How to Identify a Low Shank Sewing Machine
Identifying whether your machine is low shank doesn’t require technical expertise. Here’s a step-by-step approach to check:
Step 1: Raise the Presser Foot
Before you start measuring, lift the presser foot lever so the presser foot is in its highest position.
Step 2: Locate the Presser Foot Holder
Find the metal piece (presser foot holder) on the presser bar where the presser foot is attached.
Step 3: Measure the Distance
- Use a small ruler or measuring tape.
- Measure from the bottom of the presser foot holder (where it meets the foot) to the center of the screw that holds it.
Step 4: Check the Measurement
- Low Shank: Around 3/4 inch (0.75 inches or 18-19mm).
- High Shank: Usually 1 inch or higher (around 25mm).
If your measurement is close to 3/4 inch, congratulations—you have a low shank sewing machine!
Why Does Shank Type Matter?
You might wonder why this measurement even matters. The reason is simple but significant: shank type directly affects compatibility with presser feet, quilting attachments, walking feet, and other add-ons you might want to use.
A mismatch can lead to:
- Difficulty installing attachments.
- Poor fabric feeding or tension issues.
- Damaged accessories.
Most domestic or home sewing machines are low shank, making it easier for hobbyists and beginners to find compatible accessories.
Key Features of Low Shank Sewing Machines
Low shank machines are favored in many households and for good reason. Let’s look at their most notable features:
1. Compatibility

Benefits of Low Shank Sewing Machines
Choosing a low shank machine offers several practical advantages, especially for hobbyists, home sewers, and quilters.
1. Easy to Find Accessories
Because most domestic machines are low shank, sewing stores and online suppliers offer a wide range of presser feet and attachments that fit perfectly.
2. Cost-Effective
Low shank accessories tend to be more affordable and more readily available than their high shank counterparts.
3. Wide Brand Compatibility
Brands like Singer, Brother, Janome, and Bernina (with adapters) often use the low shank system in their home models.
4. Adaptable
If you upgrade your machine within the low shank class or even change brands, many of your favorite accessories will still work.
Challenges with Low Shank Sewing Machines
No sewing system is without its quirks. Here are a few challenges you might encounter:
1. Limited Compatibility with Industrial Attachments
Many industrial presser feet or specialty attachments are made for high shank machines, so they won’t fit a low shank model.
2. Adapters Needed for Certain Accessories
Some high-end or specialized feet (like certain free-motion or walking feet) are designed for high shank machines. You may need adapters, which can sometimes affect stability.
3. Less Clearance for Thick Fabrics
Low shank machines usually have less vertical space between the needle plate and the presser bar, making it harder to sew very thick or bulky layers.
Practical Tips for Low Shank Sewing Machine Owners
Set up for success and get the most from your sewing machine with these simple tips:
1. Always Double-Check Attachment Compatibility
Before purchasing a new presser foot, check if it’s labeled “low shank compatible.” Look for measurements or ask a sales associate if unsure.
2. Use Adapters Wisely
If a must-have attachment is only available for high shank machines, look for a sturdy, well-reviewed low-to-high shank adapter. Remember that some adapters may affect sewing smoothness.
3. Maintain Your Machine Regularly
Keep the shank area free from lint, dust, and thread tangles. Clean and oil your machine as per the manufacturer’s guidelines.
4. Store Accessories Safely
Use a case or box for your attachments to prevent loss or damage, and label them with “low shank” for quick identification.
5. Test Before Large Projects
Whenever you try a new foot or attachment, practice on scrap fabric to ensure correct fit and performance.

Upgrading or Changing Your Presser Feet
If you love experimenting with different presser feet for things like quilting, hemming, or decorative stitches, stick with a low shank sewing machine or make sure to have a quality adapter if you switch to another style.
Steps for Upgrading Attachments:
- Measure your machine’s shank height.
- Identify if a new foot is meant for low shank.
- If not, check if an adapter is available for your machine.
- Pass new accessories through a trial run with scrap materials.
Troubleshooting Common Low Shank Attachment Issues
Sometimes, even with a low shank machine, you may encounter fitting issues. Try these troubleshooting tips:
- Attachment Won’t Fit: Confirm you’ve removed the generic snap-on adapter; some feet require direct attachment to the shank.
- Poor Stitch Quality: Check for proper installation—tighten screws securely.
- Unstable Presser Foot: If using an adapter, ensure it is tightly fastened.
When in doubt, consult your machine’s manual or seek advice from your local sewing store.
