Buy the SINGER Heavy Duty 4423 if your pile of pants is mostly jeans, and the Brother XM2701 if it's mostly dress pants and kids' clothes. Hemming the flat part of a leg is easy on any machine. The test is the side seam, where a double-folded jeans hem stacks six or more layers of denim, and the presser foot has to climb that lump without stalling or skipping. Foot lift, presser foot pressure and a free arm decide that. Stitch count doesn't.

How we picked these machines
We pulled Amazon's search results for hemming jeans and hemming pants on October 13, 2026, then checked each machine's listing for the features that matter on a pant leg: presser foot lift, adjustable presser foot pressure, a free arm and the feet in the box. Sales did the first cut. The Brother XM2701 showed 4,000+ purchases in the past month and the SINGER 4423 showed 1,000+. A machine had to carry a large owner base too, so a new model with a few dozen ratings didn't make it over one with thousands.
This is a spec review. We compared listings, manuals and owner feedback; we did not hem pants on every machine here. How we research.
Why jeans hems are hard: count the layers
A jeans hem is folded twice. Across most of the leg that's three layers of denim under the needle. At the outseam and inseam, where the leg's own seam allowances are folded in too, the stack jumps to six, and on a flat-felled inseam it can reach eight or more. The foot rides up that step, tilts nose-up, and the feed dogs lose their grip. That's when stitches skip, the needle bends, or the machine just stops.
Three machine features make that step easy. An extra-high presser foot lift lets you slide the stack under the foot to start with. Adjustable presser foot pressure lets you ease off so the foot doesn't clamp the bulk and stall. A free arm lets the leg wrap around the machine so you sew the hem in the round instead of opening the seam. Both SINGER picks list the first two; both Brother picks list the free arm.
The 5 best sewing machines for hemming pants
SINGER Heavy Duty 4423
The 4423 lists the two features a jeans hem leans on hardest: an extra-high presser foot lift so the folded stack fits under the foot, and adjustable presser foot pressure so you can ease the foot over the side seam. Singer describes the motor as 50% more powerful than its standard machines. That's the push you want at the thickest point, and the 1,100 stitches per minute top speed is there for the long flat stretch of a curtain hem.
It's also one of the most owned machines on Amazon, with a 4.6-star average from more than 21,000 ratings and a #14 rank in Sewing Machines on October 13. With that many owners, any hemming question you have has already been asked and answered somewhere.
- Stitches23 (97 applications)
- Speed1,100 stitches/min
- Presser footextra-high lift, adjustable pressure
- Bobbintop drop-in
- Frameheavy-duty metal
- Weight17.1 lb
Why it stands out
- Extra-high foot lift and adjustable foot pressure for the side seam
- Metal frame keeps it planted when you push through bulk
- Huge owner base for help and tutorials
Think twice if
- You mostly hem dress pants and want a blind hem foot in the box (check the accessory list)
- You want a speed limiter for slow, careful work
SINGER Heavy Duty 4452
The 4452 is the 4423's bigger sibling, and for hems its accessory kit is the reason to pay a bit more. The listing puts a walking foot, a non-stick foot and a clearance plate in the box. The clearance plate is Singer's version of a hump jumper: it sits under the foot so it climbs the side seam level. The walking foot helps when a stretch denim hem wants to creep and twist.
Heavy-duty needles come in the kit too, so you can hem a pair of work jeans the day it arrives. It ranked #6 in Sewing Machines on Amazon when we checked, with more than 11,000 ratings.
- Stitches32 (110 applications)
- Speed1,100 stitches/min
- Includedwalking foot, non-stick foot, clearance plate, heavy-duty needles
- Bobbintop drop-in
- Weight14.6 lb
Why it stands out
- Clearance plate and walking foot included
- More stitches for knit and stretch hems
- Heavy-duty needles in the box
Think twice if
- You only hem a few pairs a year; the 4423 or XM2701 does it for less
Brother XM2701
For dress pants, chinos, school uniforms and kids' jeans, this is plenty of machine. Its 27 stitches include a blind hem stitch for trousers and stretch stitches for knit pants, and Brother's own listing pitches the free arm for "cuffs, sleeves, and pant legs." It comes with a twin needle, which is the easy way to hem leggings and knit joggers with two neat parallel rows.
It's Amazon's #2 sewing machine, with 4,000+ purchases in the past month. Be realistic about heavy denim: it's a light, compact machine, so work slowly over the side seam, use a hump jumper, and turn the handwheel by hand for the thickest stitches.
- Stitches27 incl. blind hem and stretch
- Feet6
- Free armyes
- Needle threaderautomatic
- Bobbindrop-in top
- Extrastwin needle, 3 needles, 4 bobbins
Why it stands out
- Blind hem and stretch stitches cover dress pants and knits
- Free arm and twin needle included
- Lightweight and easy to store
Think twice if
- Most of what you hem is heavy work denim or canvas
Brother ST371HD
If you hem for the whole family, the ST371HD's box contents save a trip to the store. It includes a blind stitch foot for dress pants, a non-stick foot for faux leather and coated fabric, a zipper foot for the other alterations that turn up, and a needle set that runs up to size 16, the usual jeans-hem size. Brother calls it its "Strong & Tough" model, and it has the free arm for sewing the leg in the round.
- Stitches37 incl. auto-size buttonhole
- Feet6 (zigzag, non-stick, blind stitch, zipper, buttonhole, button)
- Needles#11, #14, #16 + twin
- Free armyes
- Framemetal
Why it stands out
- Blind stitch foot in the box for invisible trouser hems
- Needles up to #16 plus a twin needle
- Lifetime phone and chat support from Brother
Think twice if
- You need adjustable presser foot pressure (the listing doesn't mention it)
Janome HD3000
At 23 pounds the HD3000 is the heaviest machine here, and for hemming that's a good thing: it doesn't creep across the table when you shove a stack of denim under the foot. Janome lists foot pressure adjustment, snap-on feet and a reverse lever on an aluminum body, and the hard case protects it between alteration sessions. It's a simple dial machine with 18 stitches, which is all a hem needs.
It costs the most of the five and sells in far smaller numbers on Amazon (50+ a month when we checked). Read our Janome HD3000 review for the full spec sheet and how it compares with the HD1000 and HD5000.

Setup for a factory-looking jeans hem
| Setting | Jeans | Dress pants |
|---|---|---|
| Needle | Jeans 90/14 to 100/16, new | Universal 80/12 |
| Top thread | Topstitching or jeans thread for the look; all-purpose works | All-purpose polyester, matched color |
| Bobbin thread | All-purpose polyester | All-purpose polyester |
| Stitch | Straight, about 3 mm long | Blind hem |
| Speed | Slow at the side seams; handwheel for the thickest stitches | Steady |
- Mark the new length with the pants on, then add about 1 inch for a double-folded jeans hem.
- Cut, fold up 1/2 inch, press, fold again, press hard. A hot, heavy press flattens the side seam before the machine ever meets it.
- Sew a test hem on a scrap from the leg you cut off, folded the same way, crossing a seam. Check the back for loops.
- Start sewing just past a side seam, so the foot is already level when you reach the next one. Slide a hump jumper under the heel of the foot as you climb onto the seam, then move it to the front as you come off.
- Overlap the stitching by an inch where you started, then press again.
If the stitches loop on the back, the top thread usually isn't seated in the tension discs. Our sewing machine tension problems guide walks through the fix, and skipped stitches on thick fabric gets its own page.
Keeping the original hem
Many people want the faded factory hem back on the shorter jeans. Cut the leg an inch below the finished length you want, then fold the original hem up so its bottom edge sits at the new length (the cut edge points up inside the leg). Stitch right against the top of the factory hem with the jeans needle, trim the fold to about 1/2 inch, finish the edge with a zigzag, and press the fold up into the leg. Done well, the new seam hides under the old hem's edge.
Dress pants and the blind hem
Fold the hem up, then fold it back on itself so about 1/4 inch of the raw edge sticks out to the right. The blind hem foot's guide runs along that fold. Most of the stitches land in the hem allowance, and every few stitches one zigzag bites the fold. Adjust the stitch width so the bite catches only a thread or two. On the right side, it shows as a row of tiny dots.
What about handheld mending machines?
Skip them for hems. The Singer Stitch Sew Quick is a top seller, but its own listing calls it a single-thread machine for "quick repairs or temporary basting" that "works best on lightweight fabrics," and it averages 3.3 stars from more than 11,600 ratings. A chain stitch unravels when one end comes loose, and none of these clip-on machines can climb a denim side seam. If you're short on space, a compact full-size machine like the XM2701 or one from our best portable sewing machine guide is the better buy.
Small things that make hems easier
- Madam Sew Bulky Seam Jumper: two thicknesses (1/8 and 3/16 inch) to level the foot at the side seam. The cheapest fix for skipped stitches on jeans.
- SINGER Heavy Duty needles in 90/14, 100/16 and 110/18, one of Amazon's top needle sellers. Or SCHMETZ Jeans needles in an assorted pack.
- SINGER Blue Jean thread in old gold, a heavy polyester that copies the factory topstitching color. For a thicker look, Gutermann Denim 12 wt comes as six spools; use it on top only, with all-purpose thread in the bobbin.
- A magnetic seam guide keeps the stitching an even distance from the fold all the way around the leg.
Which one to buy
If your hemming pile is jeans, buy the SINGER Heavy Duty 4423 and a hump jumper. If you hem heavy work denim every week, step up to the SINGER 4452 for its clearance plate and walking foot. For dress pants, chinos and knits, the Brother XM2701 has the blind hem stitch and free arm for less money. Planning to do more than hems?
