When ordering ribs at a restaurant it's not uncommon to see the terms "full-rack" and "half-rack" listed. However, that often doesn't tell the person how many ribs they'll actually get.

A typical slab/rack of pork ribs is 10-13 ribs. Meaning, a half rack of ribs would contain 5 or 6 individual rib bones.

What is a "Slab" or "Rack" of Ribs?

Pork ribs are sold as "slabs." For the sake of this article, you can think of this as a "full rack" of ribs.

Depending on the breed of pig, they will have 15-16 rib bones. However, when a hog is butchered, 2-3 bones are left in the shoulder, and smaller bones are also trimmed with the discretion of the butcher.

In a grocery store, you should expect to see at least 10-13 bones in a slab or "full rack" of pork ribs.

In my example above, the baby back ribs have a total of 13 ribs. If we were to turn these into "half racks" - each person would receive 6 ribs and the 13th would likely be removed as there is very little, if any meat.

Fun-fact: If you have less than 10 bones, you have what's called a "cheater" rack.

Is a Half Rack for Baby Back Ribs or Spare Ribs?

When ordering from a restaurant (not a barbecue joint) the ribs you're eating are likely baby back ribs.

However, if you're eating at a barbecue joint - they will likely make the distinction and say whether or not they sell spare ribs (explained below).

There are distinct differences between spare ribs and back ribs.

In terms of serving sizes:

  • Baby back ribs will offer 1-2 servings - hence a half rack.
  • Spare ribs will offer 2-4 servings because the ribs are bigger.

Baby back ribs come from the upper portion of the rib cage, where the ribs and spine meet - which is loin meat.

Pictured below:

Pork spare ribs are taken from the bottom of the ribs or the underbelly of the hog - where the pork belly (and bacon) come from.

Spare ribs can also be St. Louis cut or "center cut." All this means is that they're trimmed to remove the sternum, costal cartilage, and flap. This process creates a more traditional "rack" of ribs.

Spare ribs are meatier and have more flavor (due to the fat content). However, they are less tender than baby back ribs which come from the loin. The pork loin is known for being a very lean cut of meat and contains very little intramuscular fat.

Rather than taking my word for it, I went to a number of different restaurant's websites to see what their menus showed.

Below is a quick breakdown:

  • Chili's Website shows a picture of half rack of ribs with 5 ribs bones.
  • Applebee's Website shows a picture of a half rack of ribs with 6 rib bones.
  • Texas Long Horn's Website shows a picture of a half rack of ribs with 6 rib bones.

Note: All of these restaurants sell baby back ribs.

For even further comparison, a popular BBQ joint in my area is Big Fatty's BBQ; Big Fatty's sells spare ribs not baby backs. On their menu they state the following:

  • 1/2 Slab* (6 ribs avg.)
  • 1/4 Slab (3 ribs avg.)

*Again, Slab means rack - so a half-slab is a half-rack.

So even in terms of spare ribs, we have the same number as baby backs. The reason they say "average" is because most barbecue joints sell meat based on weight, not the number of ribs.

How many ribs is a half rack?

Half racks contain six to eight individual ribs with each bone about one inch thick. When deciding how much meat you want on the plate, this is often an easier option than buying full racks as they provide plenty of meat per portion without being too big.

How much does a half rack of ribs feed?

If you are planning on making the ribs the main part of your meal, here is a rough guide: Count on half a rack, or six ribs per person if you are serving baby back ribs. Aim for four or five ribs per guest if you are serving spare ribs. Plan for two or three ribs per guest if you are cooking up beef back ribs.

How big is half rack of ribs?

Although a half rack of ribs is smaller than a full rack, it's still a pretty large portion. Typically, a full rack of ribs averages 10 to 13 ribs that are 3 to 6 inches long and weigh about 1 1/2 to 2 pounds. That means a half rack would fall somewhere around five to six ribs and weigh 12 to 16 ounces.
