Pretzel chips, hard, plain calories: 105 per 1 small bag (28 g)
This exact USDA record reports 105 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 105 calories for 1 small bag at 28 grams. On a fixed-weight basis, the same record contains 375 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 2.7 g protein, 0.9 g fiber, and 571 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 97.6% of the record’s listed input weight. The record contains 2 source-input rows in all. 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 10–319 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 2708256: “Pretzel chips, hard, plain.” 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 2708256, each row multiplies the published per-100-gram values by its stated weight. “1 pretzel chip/crisp/thin” 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 chip/crisp/thinUSDA-listed household measure | 2.7 g | 10 kcal | 0.3 g | 0.1 g | 55 mg |
| 1 small single serving bagUSDA-listed household measure | 28 g | 105 kcal | 2.7 g | 0.9 g | 571 mg |
| 1 large single serving bagUSDA-listed household measure | 85 g | 319 kcal | 8.3 g | 2.8 g | 1,734 mg |
02 · Fixed-weight context
Where 100 grams sits inside Pretzels/snack mix
The comparison set contains 37 exact records in the Pretzels/snack mix USDA category. Here, “middle half” describes FDC 2708256’s energy position in that corpus—not nutritional quality, desirability, or a health rating.

03 · FDA label lens
The strongest strength-side and tradeoff-side signals
At FDC 2708256’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 “Pretzel chips, hard, plain,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2708257 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 pretzel chip/crisp/thin to 1 large single serving bag
USDA assigns those measures 2.7 g and 85 g. At this record’s fixed composition, scaled energy moves from 10 kcal to 319 kcal.
- 02
Record choice: compare with FDC 2708257
At an equal 100 g, this record has 420 mg less sodium than “Pretzel chips, hard, flavored.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Snacks, pretzels, hard, plain, salted
The source formulation has 2 input rows; Snacks, pretzels, hard, plain, salted supplies 97.6% of listed input weight. Those are standardized formulation inputs, not final plated percentages.
05 · Exact-record choice
Select by literal evidence, not the shortest name
Keep this record when “hard; plain” fits. Inspect FDC 2708257 when “hard; flavored” is the more literal description of the food and preparation.

Formulation evidence
The listed formulations differ
The formulation rows differ, but the source data do not isolate which component caused any nutrient difference. Input weights describe the standardized formulation—not final plated proportions.
Shared listed inputs: Snacks, pretzels, hard, plain, salted; Salt, table.
The ingredient codes overlap, while at least one listed amount, weight, sequence, or formulation detail differs.
Portion evidence
The listed portion sets match
This record’s reference amount is 28 g; a familiar listed measure is 1 small bag (28 g).
The comparison record’s reference amount is 28 g; a familiar listed measure is 1 small bag (28 g).
Use the 100-gram row to compare FDC 2708256 with FDC 2708257 at equal mass; use their 28 g and 28 g source amounts only for portion matching.
Evidence boundary: FDC 2708256 versus FDC 2708257 is a comparison of standardized source records—not a measurement of your meal, an overall food-quality rank, or proof that one input caused a difference.

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 “Pretzel chips, hard, plain,” 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 2708256 comes from FoodData Central Survey Foods (FNDDS). Its 375 kcal per 100 g becomes 105 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: 2708256
FNDDS food code: 54408105
The scaling for FDC 2708256 can be exact while the match to “Pretzel chips, hard, plain” is wrong. That is why this profile keeps its 28 g weight, 2-row source formulation, and selection uncertainty beside the arithmetic.
