How Big Is A Beef Tenderloin? | Buyer’s Size Guide

A whole beef tenderloin averages 5–7 lb and 20–26 inches; trimmed center-cut roasts are usually 2.5–4 lb.

Typical Beef Tenderloin Size And Weight Ranges

Here’s what you’ll see in the case. Untrimmed pieces sold as PSMO—short for peeled, side muscle on—land in the five to six pound window, and many distributors label them “5 & Up.” That tag means each individual muscle weighs at least five pounds. Trade specs use the same language and tie the item to IMPS/NAMP 189A, which standardizes trimming across vendors. You’ll also spot larger pieces that push seven to eight pounds from heavier cattle, along with trimmed roasts in the three to four pound range for smaller tables. Industry pages and packer sheets reflect those bands clearly (search “5 & Up tenderloin” in spec sheets from beef packers to see the labeling in action).

Across the length, the muscle runs long and narrow. Expect roughly twenty to twenty-six inches for a full piece, with a thick butt at one end and a tapering tail at the other. The center holds the most even diameter, which is why butchers carve that portion into a chateaubriand or filet mignon steaks. The national beef program’s cut finder confirms the ID and naming conventions for the muscle and its sections on the official tenderloin pages.

Common Formats And Typical Weights

Format	Typical Weight	Notes
Whole tenderloin, PSMO (IMPS 189A)	5–7 lb	Chain on; light surface fat; needs trimming.
Large whole tenderloin	7–8+ lb	From larger cattle; extra tying evens thickness.
Center-cut roast (chateaubriand)	2.5–4 lb	Even cylinder from the middle section.
Butt/Head roast	3–4 lb	Thick end; great for roasting and tidy slices.
Tail / tips	1–2 lb	Tapered end; ideal for medallions or stir-fry.
Filet mignon steaks (from center)	6–10 oz each	Cut 1.5–2 inches thick for even searing.

For readers who want context on where it sits on the loin, the meat cuts buying guide lays out the big picture in plain terms. That background helps you order exactly what you want, whether you’re planning a centerpiece roast or a round of steaks.

What “5 & Up” And IMPS Numbers Mean

Wholesale sheets use IMPS/NAMP codes so restaurants, retailers, and caterers can speak the same language. For this muscle, you’ll see 189 (full tenderloin), 189A (full, side muscle on, defatted), 190 (side muscle off, defatted), and 190A (side muscle off, skinned). Distributors add a size grade like “5 & Up” to signal that each piece in the case clocks in at five pounds or more. Many packers publish versions of the same spec so buyers can compare programs by grade and size. You can confirm the tenderloin ID on the industry cut page and match it to the IMPS list from the USDA Agricultural Marketing Service.

Those codes don’t lock length to an exact inch, but they do anchor weight and trimming. At warehouse clubs, PSMO bags usually ride in that five to seven pound range. Specialty shops often sell cleaned roasts already tied for the oven at three to four pounds. If you want the best price per pound, buy the full PSMO and do a quick trim at home.

How Much To Buy For A Crowd

Portion planning gets easy once you separate raw weight from cooked yield. Lean roasts shed moisture during cooking and trimmed muscles lose a bit to silver skin, chain, and surface fat. A practical rule is six to eight ounces cooked per guest. On the raw side, a five to six pound PSMO, trimmed and roasted to medium-rare, commonly serves ten to twelve people with sides. A smaller center-cut roast at three pounds suits six to eight plates.

Foodservice references publish average cooking yields that help you translate raw pounds to plated ounces. USDA tables present yield percentages for beef roasts that line up with home kitchen results, which makes planning simpler. If you need to stretch servings, slice thinner medallions across the grain and fill the platter with vegetables and a starch for balance. You can review federal cooking-yield tables to see typical loss ranges for beef roasts on the USDA yield PDF.

Quick Planner Table

Yield And Serving Estimates

Raw Piece	Typical Loss (trim + cook)	Feeds (6–8 oz cooked)
3 lb center-cut roast	25–30%	6–8 guests
5 lb PSMO, trimmed and tied	30–35%	9–11 guests
6 lb PSMO, trimmed and tied	30–35%	11–12 guests
7–8 lb large piece	30–35%	13–16 guests

The national beef program describes the muscle as long, narrow, and lean and anchors it to IMPS 189 on its public cut pages. You can scan the details, names, and related cuts on the official tenderloin entry. That page pairs well with the USDA IMPS list so your butcher request uses the same language that suppliers see.

Sections Of The Muscle And What They’re Good For

Butt (head): the thickest end. It’s a natural roast that carves into wide slices and feeds a crowd. Tie it in a few spots for even thickness.

Center: the neat cylinder prized for a chateaubriand or for slicing into steaks. This is where most filet mignon portions come from, which is why the center is popular during holidays.

Tail and tips: slender and quick-cooking. They shine in fast sears, skewers, stir-fry, or as medallions. Many shops package tails by the pound; save them for a weeknight skillet meal.

How Trimming Changes Weight

PSMO pieces arrive with the chain attached and a firm band of silver skin. Removing the chain, peeling the silver skin, and tidying any flake fat changes raw weight before you season. Expect fifteen to twenty-five percent raw trim loss, depending on how clean your butcher delivers the muscle. After trimming, tie at intervals so the roast keeps a round shape in the oven.

During cooking, moisture loss adds another ten to twenty percent, influenced by oven temperature and doneness. A gentler oven with a quick high-heat finish gives you modest shrink and a better crust. Probe the thickest point and pull five degrees below your target; carryover finishes the job while you set the platter.

Storage, Handling, And Sizing Tips

Vacuum-bagged PSMO keeps well in the coldest zone of the fridge. If the bag is tight and the pack date fits the stated shelf life, you have time to plan. For a party, buy one week ahead, then trim, tie, and salt a day in advance so the roast seasons evenly. A uniform shape helps you hit the same doneness from edge to edge.

Shopping by size is simple. For eight to ten guests, a five to six pound bag gives you a nice margin. For a smaller table, ask the butcher for a three to four pound center section. If a large case is the only option, split it: one tied roast for tonight, steaks from the middle, and a stash of tips for quick meals.

Close Variants You’ll See On Labels

Retail labels change with trimming. “Full, side muscle on” lines up with 189A. “Side muscle off” points to 190 or 190A. “Chateaubriand” signals the center section tied as a roast. “Tenderloin tails” are small, tapered pieces often sold by the pound. Many brands print a grade or program next to the size tag, and some list “5 & Up” on the sticker to flag larger pieces.

Distributors and packers publish specs that echo the same size language, including 5-plus-pound pieces per bag. You’ll see that wording on product pages across beef companies and in case labels built for restaurants and retailers. That’s why you often find five to seven pound bags in club stores and specialty counters.

Buying Smart: Weight, Yield, And Budget

The most budget-friendly buy is a full PSMO in the bag. You do the trimming, then choose how to portion it: a roast from the center, steaks from the middle, and quick-cook pieces from the tail and chain. Pre-trimmed roasts save time but cost more per pound. If you’re paying for convenience, ask how much was trimmed away so you can compare true yield against a whole piece.

Restaurant buyers run a butcher’s test for this exact reason. The method weighs the piece before and after trimming and again after cooking. The math gives the edible-portion cost, which is the number that matters to your budget at home too. A quick kitchen-scale check provides the same clarity before guests arrive.

Sizing Notes For Special Dishes

Beef Wellington: a smooth center section in the three to four pound range is the sweet spot for even shape and tidy slices. Square the ends before wrapping so the pastry cooks evenly.

Steak night: a full center can deliver six to ten steaks cut at one and a half to two inches thick. Trim the silver skin fully so each steak sears cleanly without curling.

Mixed menu: roast the head for a centerpiece, cut steaks from the middle, and save tails for a quick skillet dinner the next day. One whole piece can cover an entire weekend menu with ease.
