Pretzels, hard, plain, salted calories: 108 per 1 small bag (28 g)
This exact USDA record reports 108 calories for 1 small bag (28 g). That answer belongs to this description and weight; it is not a universal value for every meal that shares the name.

The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 108 calories for 1 small bag at 28 grams. On a fixed-weight basis, the same record contains 384 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 2.8 g protein, 1 g fiber, and 314 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is snacks, pretzels, hard, plain, salted, representing 100% of the record’s listed input weight. These are provenance for a standardized calculation, not a recipe for your plate.
The source calls its underlying survey portion “Quantity not specified,” but it separately lists 1 small bag at the identical weight. We use the familiar household label here without changing the source calculation.
The household measures attached to this record span roughly 4–326 calories across the listed portions. That is a set of scaled examples—not a confidence interval, a recommendation, or a claim about the full universe of recipes.
Calculated from the smallest and largest usable household measures listed by USDA for this exact FNDDS record; not a confidence interval.
Record-specific decision brief
What the numbers say—and what choice still belongs to you
This analysis belongs to USDA FDC 2708249: “Pretzels, hard, plain, salted.” It separates gram-weight arithmetic, corpus context, label signals, and record selection so one number does not have to answer four different questions.
01 · Portion arithmetic
Three weights, one fixed composition
For FDC 2708249, each row multiplies the published per-100-gram values by its stated weight. “1 pretzel stick” through “1 large single serving bag” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 pretzel stickUSDA-listed household measure | 1 g | 4 kcal | 0.1 g | 0 g | 11 mg |
| 1 small single serving bagUSDA-listed household measure | 28 g | 108 kcal | 2.8 g | 1 g | 314 mg |
| 1 large single serving bagUSDA-listed household measure | 85 g | 326 kcal | 8.5 g | 2.9 g | 952 mg |
02 · Fixed-weight context

03 · FDA label lens
The strongest strength-side and tradeoff-side signals
At FDC 2708249’s 28 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Iron; the larger tradeoff-side percentage is Sodium. Percentages use FDA label Daily Values, whose general “high” guide begins at 20% Daily Value. This is not an overall score or a personalized target.

04 · Highest-impact checks
The three levers most worth resolving first
For “Pretzels, hard, plain, salted,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2708250 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 pretzel stick to 1 large single serving bag
USDA assigns those measures 1 g and 85 g. At this record’s fixed composition, scaled energy moves from 4 kcal to 326 kcal.
- 02
Record choice: compare with FDC 2708250
At an equal 100 g, this record has 435 mg more sodium than “Pretzels, hard, plain, lightly salted.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: Snacks, pretzels, hard, plain, salted
USDA derives this record from one listed source-input row at 100 g. Real preparations can still differ in water, cooking state, brand, and served weight.
05 · Exact-record choice
Select by literal evidence, not the shortest name
Keep this record when “hard; plain; salted” fits. Inspect FDC 2708250 when “hard; plain; lightly salted” is the more literal description of the food and preparation.

Uncertainty, made actionable
What can change this estimate?
This is a standardized USDA survey-food profile, not a measurement of every preparation. Actual nutrition can change with piece or portion size, recipe or brand, fillings or frosting, added fats and sugars.
For “Pretzels, hard, plain, salted,” resolve piece or portion size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
piece or portion size
When composition is held constant, nutrient totals scale directly with grams. A 20% weight correction produces the same 20% correction to the scaled totals.
- 02
recipe or brand
Prefer a package, menu, or known recipe when it identifies the food more precisely. Otherwise preserve the generic record as an explicit approximation.
- 03
fillings or frosting
Check whether the exact source description already includes it. If not, keep the addition separate rather than silently folding it into the base record.
- 04
added fats and sugars
Match the named cooking-fat state when possible. Fat used, retained, or left behind is preparation information that a dish name alone cannot recover.
How we estimated this
The arithmetic is simple; the provenance is the point
FDC 2708249 comes from FoodData Central Survey Foods (FNDDS). Its 384 kcal per 100 g becomes 108 kcal at 28 g through nutrient per portion = nutrient per 100 g × portion grams ÷ 100; this page adds no second nutrition estimate.
About the serving label: USDA describes the underlying survey portion as “Quantity not specified.” The separately listed 1 small bag has the same gram weight, so the familiar label can be shown without changing the calculation.
Data cycle: 2021–2023, published October 31, 2024
FoodData Central ID: 2708249
FNDDS food code: 54408016
The scaling for FDC 2708249 can be exact while the match to “Pretzels, hard, plain, salted” is wrong. That is why this profile keeps its 28 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
