The 8 Best Keurigs for Small Spaces, Reviewed
The slimmest all-rounder first, then the minis, the iced and budget picks, and the roomier models.
Keurig K-Slim Single Serve Coffee Maker
The best balance of slim and practical. It’s under 5 inches wide yet holds a 46-ounce reservoir, enough for about four cups before refilling, and it has more ratings than any other Keurig here, over 63,000.
MultiStream brewing extracts more evenly, the drip tray lifts out for travel mugs up to 7 inches tall, and it switches off 5 minutes after the last brew. Tom’s Guide called it the best introduction to the Keurig line and timed cups at under 2 minutes, though it measured 74 dB.
- Slim with a real reservoir
- 63,000+ ratings
- Fits tall travel mugs
- About 17 inches tall
- Fairly loud, per Tom’s Guide
Keurig K-Mini Mate Single Serve Coffee Maker
The smallest Keurig here, at just under 4 inches wide and about 9.5 inches tall, so it tucks onto a desk, a dresser or the tiniest counter. Tom’s Guide names it the best budget Keurig and says it replaces the original K-Mini as Keurig’s smallest model.
There’s no tank: you pour in one cup of water each time, up to 12 ounces, and it fits a travel cup up to 7.25 inches tall. Tom’s Guide found the coffee “quite weak,” so pick a bold pod. It comes in four colors.
- Smallest footprint
- Lowest price tier
- Short enough for low shelves
- Refill for every cup
- Weak coffee, per Tom’s Guide
Keurig K-Express Single Serve Coffee Maker
One of Amazon’s best-selling Keurigs, with over 58,000 ratings, in the lowest price tier. A Strong Brew button makes a bolder cup, and the 42-ounce reservoir covers about four cups.
At 5.1 inches it’s a hair wider than the K-Slim, and the removable drip tray fits travel mugs up to 7.4 inches. It shuts off 5 minutes after brewing and works with the My K-Cup reusable filter if you want to use your own grounds. Colors vary in price.
- Strong Brew button
- 58,000+ ratings
- Takes your own grounds with My K-Cup
- Just over 5 inches wide
- About 17 inches tall
Keurig K-Iced Single Serve Coffee Maker
Made for iced coffee. It starts brewing hotter to pull out flavor, then cools down for less ice melt, and the 8-, 10- and 12-ounce sizes include the ice. A Strong Brew button handles your hot coffee too.
It’s 5.1 inches wide but only about 12.6 inches tall, so it slides under low cabinets. The 42-ounce reservoir brews about four cups, the tray fits tumblers up to 7 inches, and it works with the My K-Cup filter for your own grounds.
- Brew-over-ice setting
- Short enough for low cabinets
- Strong Brew button
- Just over 5 inches wide
Keurig K-Mini Mate Plus Single Serve Coffee Maker
The K-Mini Mate’s bigger sibling fixes its main drawback with a 50-ounce removable reservoir, so you brew several cups before refilling. It’s still under 5 inches wide and about 9.5 inches tall.
It adds brew-over-ice and Strong Brew settings, plus three cup sizes: 8, 10 and 12 ounces. It’s newer, with about 500 ratings so far, and comes in three colors.
- Biggest tank of the minis
- Low height
- Iced and strong settings
- Fewer ratings so far
- Deeper than the Mini Mate
Keurig K-Supreme Gen 2 Hot and Iced Coffee Maker
Tom’s Guide names the K-Supreme its best Keurig overall, and this Gen 2 version launched as Amazon’s #1 new release in single-serve brewers. It adds three strength and three temperature settings, brew-over-ice and MultiStream brewing.
It’s wider at 8 inches but short at 11.5 inches, and the 72-ounce reservoir has a handle for easy refills. Four cup sizes run from 6 to 12 ounces, and it works with the My K-Cup filter. It’s new, with about 100 ratings so far.
- Biggest reservoir here
- Strength and temperature control
- Only 11.5 in tall
- 8 inches wide
- Few ratings so far
Keurig K-Compact Single Serve Coffee Maker
The no-fuss pick. Smart Start heats and brews in one step, so you pop in a pod and press a size without waiting. The 6-ounce setting makes the strongest cup, and opening the handle without a pod gives you hot water for tea or oatmeal.
The 36-ounce reservoir lifts off for refilling, the drip tray fits travel mugs up to 7 inches, and it turns off 2 hours after the last brew. Despite the name, Amazon lists it at 8.2 inches wide, so measure before you buy.
- Simple button controls
- Hot water on demand
- 11,000+ ratings
- Listed at 8.2 in wide
- Smallest tank here
Keurig K-Café SMART Single Serve Coffee Maker with Frother
The one Keurig here that makes lattes. Tom’s Guide names the K-Café its best Keurig for milky drinks, and this SMART version has a built-in hot and cold frother plus 2- and 4-ounce coffee shots for lattes and cappuccinos.
It’s the widest pick at 11 inches, so it suits a small kitchen with a coffee corner more than a dorm. Wi-Fi BrewID recognizes your pod, the app schedules brews, and you get five strength and six temperature settings. At 4.5 stars, it’s the top-rated Keurig here.
- Lattes and cappuccinos
- Top-rated Keurig here
- Brew from your phone
- Widest pick (11 in)
- Top price tier

How to Keep a Small Keurig Brewing Well
- Descale every 3 to 6 months with a descaling solution, then run a few cycles of clean water to rinse.
- Wipe the pod holder and drip tray weekly so grounds and drips don’t build up.
- Empty and rinse the reservoir now and then, especially if the machine sits unused.
