Brother 1634D review
VerdictSpecs checked against Brother data · Checked Sep 2026
7.5/107.5
out of 10
The 1634D is the 1034D in mass-retail clothing: the same 3/4 thread, 1,300 spm, differential feed serger with a removable free arm, worth buying only when it is cheaper than the 1034D on the day.
Who it's for
A first serger buyer who finds the 1634D on sale at a big-box store and wants the Brother platform with the 25-year limited warranty.
Skip it if
You want 2-thread stitches, air threading, a coverstitch, or a published differential feed range; the 1034DX and Juki MO-654DE answer those.

Where sources disagree
- Weight: 17.3 lb appears only in review-blog snippets (sergerpro.com, mashupfabric.com); Brother page value not captured. The related 1034D is listed at 13.88 lb by a dealer, so 17.3 lb may include packaging. Catalog will show 17.3 lb flagged [verify].
- Dimensions: 12.5 x 13.5 x 15 in from a review blog; axis order not stated. Catalog will show it flagged [verify].
- Stitch count: 22 (sergerpro.com) vs Brother, which lists stitch types without a count. Catalog will show 22 as a blog figure.
- Threading color coding: Brother says color-coded; a PatternReview owner says the 1634D does not have color coded threading but has two stitch fingers where the 1034D has one. Catalog will list Brother's wording and note the owner report.
- Differential feed ratio: not published for the 1634D in any snippet. Brother lists 0.7 to 2.0 for the 1034DX; do not carry that number across models.
- Price: $154 at Walmart in a 2019 PatternReview thread (stale). The 1634DX is $259 at Joann per the same forum. No 2026 1634D price captured; none recorded.
Manufacturer claims we quote but do not assert (4)
- "Easy to follow, color-coded lay-in threading system" (manufacturer claim, product page)
- "Perfect for finishing, creating rolled hems, inserting zippers, stitching neat blind hems, and creating ruffles" (manufacturer claim, product page)
- "One of the bestselling and most popular home serger machines" (review-blog claim, mashupfabric.com)
- "Cover Stitch Serger" appears in one dealer listing title (mistersewvac.com); the 1634D has no coverstitch function per Brother
Strengths
Same 3/4 thread, 1,300 spm core as the well-reviewed 1034D, with a removable free arm and trim trap.
Standard 130/705H household needles and three feet in the box.
Brother 25-year limited warranty at a big-box price.
Weaknesses
Very thin owner record: two PatternReview reviews against 66 for the 1034D, one reporting a rolled hem problem.
Weight, dimensions and differential feed ratio are not published by Brother on pages found; the figures online come from review blogs.
No 2-thread mode and no coverstitch, despite one dealer listing calling it a cover stitch serger.
Check before you buy
3 checks01
Compare the day's price with the 1034DForum members describe the 1034D, 1634D and 1634DX as the same function at about the same money. Buy whichever variant is cheapest that day.
02
Check for color-coded threadingBrother's page says color-coded lay-in threading; one owner says her 1634D lacked the color coding of the 1034D. Look at the thread path on the unit before buying.
03
Ignore the cover stitch labelOne dealer lists this as a cover stitch serger. The 1634D is a 3/4 thread overlocker only; a coverstitch needs a separate machine such as the Brother 2340CV.
