How Big Are Yukon Gold Potatoes? | Handy Size Guide

Yukon Gold sizes run from petite 1.5–2.25 inches to hefty 3–4.5 inches, with most grocery bulbs in the 2–3 inch, 4–10 ounce range.

Typical Yukon Gold Size Range At A Glance

Yellow-fleshed potatoes sold as “gold” come in market buckets that map to standard size designations used across the U.S. trade. For round types, the common buckets are Small, Size B, Size A, Medium, and Large. Each label reflects a band of diameters measured across the widest part of the tuber and, by extension, a typical weight span. That’s why two potatoes with different shapes can weigh the same while showing different diameters.

The quick picture: “petite” or Size B golds sit near 1.5–2.25 inches across. The workhorse category many shoppers grab, often called Size A or “medium,” runs from 1.875 inches up to around 3–3.25 inches, with a good share landing above 2.5 inches. Foodservice buyers sometimes order by weight per case—like 80-count or 100-count in a 50-pound box—which roughly translates to 8–10 ounces and 6–8 ounces per potato, respectively.

Common Size Labels For Gold-Flesh Potatoes

Label	Diameter (in)	Typical Weight (oz)
Small / Size B	1.50–2.25	2–5
Size A (retail “medium”)	1.875–3.25	4–10
Medium (trade)	2.25–3.25	5–10
Large	3.25–4.5	10–28
Creamer / Baby	0.75–1.625	1–2

Brands and growers won’t slice the bands exactly the same, but the numbers above reflect the federal standards used in grading and size naming, plus the carton-count system restaurants use day to day. If you cook by weight, a kitchen scale beats eyeballing every time. If you cook by feel, match the potatoes in a batch so they roast and steam at the same clip. For storage and prep, check sprout eyes and trim green patches; those habits pair well with potato sprout safety in any home kitchen.

How Producers Measure “Big” And “Small”

Packers gauge round potatoes by their greatest cross-section, not by length. A ring sizer or caliper does the job. When a lot is packed as Size A, at least forty percent must be 2.5 inches across or weigh six ounces or more. That’s why a sack marked as Size A often feels consistent on the cutting board. The Small and Size B bands sit below that, while “Chef” and “Large” run above three inches and into buffet-friendly territory.

For processed goods—think wedges or fries—buyers often specify a minimum of two inches in diameter or four ounces per whole potato. This keeps the pieces steady in a slicer and reduces waste. Retail bags don’t always print the band, but you’ll sense it: baby golds look marble-like; midrange golds fill a palm; big ones need two-hand prep.

Why Yukon Golds Seem Denser Than They Look

These potatoes sit in the “medium starch” camp with a moist, creamy bite. A two-inch gold can weigh more than a two-inch red because cell structure and solids vary across varieties and growing regions. That’s one reason recipes that list “1 pound of gold potatoes” deliver steadier results than “4 potatoes.” When weight matters—purées, gnocchi, gratin—the scale wins.

Diameter, Weight, And Carton Counts

Foodservice counts talk in “per 50-pound carton.” A 100-count means about half a pound across two potatoes—so around eight ounces each. An 80-count leans closer to ten ounces. Those numbers aren’t a gold-variety rule; they’re a packaging shorthand that tells you how many potatoes land in a box. Home cooks can still use the idea: larger count = smaller potatoes; smaller count = bigger ones.

Picking The Right Size For Each Job

Match the tuber to the task. Petite golds shine in whole-roasted sides, salads, and skewers. Midrange golds handle mashing, smash-and-roast, and hearty stews. Larger spuds suit hasselbacks, stuffed halves, and big pans of gratin. Texture shifts with age and storage, so taste a piece now and then and adjust salt and fat.

Broad Yield Guide

Here’s a handy yield map by size. It helps with shopping and portion planning when a recipe calls for a pound count rather than a potato count.

Handy Yield Guide By Size

Size	Pieces Per Pound	Best Uses
Creamer / Baby	8–12	Whole-roasted, skewers, quick boils
Small / Size B	5–8	Salads, sheet-pan sides
Retail “Medium”	3–4	Mash, smash, stews
Large	2–3	Hasselback, stuffed halves

Nutrition Notes Tied To Size

Nutrition scales with grams. A small raw gold at around 138 grams lands near 128 calories. A medium raw potato at around 148 grams sits near 110 calories across varieties. Per 100 grams, gold flesh brings roughly 73 calories with a solid dose of vitamin C and potassium (MyFoodData). Skin adds fiber, so leave it on when the dish allows.

How To Buy For Even Cooking

Pick bags where the shapes match. Avoid mixed lots with tiny marbles and big ovals in the same sack unless you plan to sort at home. Press gently; firm is good. Skip spuds with soft spots or a damp feel. Rinse, dry, and stash in a cool, dark spot with airflow to stretch shelf life.

Quick Sizing Tricks For Recipes

Mashed Or Purée

Choose palm-filling midrange golds. They peel fast, cut clean, and cook evenly. For silky results, rice while hot and fold in warm dairy. Salt the water; it seasons from the inside out.

Roasted Or Smashed

Go small to mid. Steam or simmer until a fork slips in, drain, then smash on a sheet and roast. The craggy edges love oil and crisp up nicely.

Stews And Soups

Pick mid to large and cube evenly. The pieces hold shape but still turn tender. Add late in the simmer to avoid mealy edges.

Bottom Line For Busy Cooks

Think in bands: 1.5–2.25 inches (baby), 1.875–3.25 inches (), and 3–4.5 inches (large format). Match pieces within a pan, shop by weight when you can, and let the job pick the size.
