Calories In Uncrustables: Sizes, Flavors, And Extras

Here’s the quick picture. The standard 58 g grocery sandwiches sit at 210 calories for peanut butter & grape jelly and the same 210 calories for peanut butter & strawberry jam. The reduced sugar wheat line brings that to 190 calories while holding the 58 g size. Big boxes for clubs and K-12 programs use larger 2.6–2.8 oz sandwiches that climb near 300–320 calories per unit. Those ranges come straight from brand labels.

Quick Calorie Reference By Popular Varieties

This table pulls the calorie line for the most common packs you’ll see in stores and cafeterias.

Product	Serving Size	Calories
Peanut Butter & Grape Jelly (grocery)	1 sandwich, 58 g	210
Peanut Butter & Strawberry Jam (grocery)	1 sandwich, 58 g	210
Reduced Sugar PB&Grape on Wheat	1 sandwich, 58 g	190
Reduced Sugar PB&Strawberry on Wheat	1 sandwich, 58 g	190
2.6 oz PB&Grape (K-12/club)	1 sandwich, 76 g	300
2.8 oz PB&Grape (warehouse pack)	1 sandwich, 80 g	320

Portions make more sense once you set your daily calorie needs. From there, it’s easy to slot a sandwich as a snack, part of lunch, or a quick pre-workout bite.

Where The Numbers Come From

Calories for each flavor and size come from the brand’s product pages and labels. The grape PB&J and strawberry jam sandwiches list 210 calories per 58 g. The reduced sugar wheat options list 190 calories per 58 g. Large 2.6 oz school units show 300 calories, and warehouse 2.8 oz units show 320 calories per sandwich. If you want a label example, the grape PB&J page is a handy reference and matches the panel on the box.

How Serving Size Changes Your Total

Size is the main lever. A jump from 58 g to 76–80 g adds bread and filling. That boosts calories, sodium, and sugars in a near-linear way. If you’re planning school lunches or stocking team snacks, match the size to the appetite and timing. The 58 g versions fit a light snack. The larger units carry closer to meal energy for kids or active adults.

Flavor Differences Are Small

Grape and strawberry sit neck and neck at 210 calories in the standard size. Macros land close too: 9 g fat, 28 g carbs, and 6 g protein for the classic PB&J. The reduced sugar wheat options shave calories mostly by trimming sugars, not by shrinking the sandwich.

Label Snapshot For The Classics

Mid-pack nutrition panels show the same calories for grape and strawberry at the grocery size. You’ll also see 8–9 g added sugar on those labels. That’s one reason some shoppers pick the wheat reduced sugar line.

How To Fit Uncrustables Into A Day

These sandwiches are handy. Keep a box frozen, thaw one at room temp for 30–60 minutes, and you’re set. That makes them practical for lunchboxes, quick desk bites, or a grab-and-go before training.

Snack, Light Lunch, Or Pre-Workout

Use the 58 g size as a mid-morning snack, a small lunch with fruit and veggies, or as carbs before exercise. The 2.6–2.8 oz sizes suit bigger appetites. Balance the day around them with lean proteins and produce.

Smart Pairings That Balance The Plate

Round out a 210-calorie sandwich with a piece of fruit and a handful of carrots. Add a glass of milk or a small yogurt for extra protein. If you’re watching sodium or added sugar at dinner, keep sides simple at that meal.

Storage, Thawing, And Food-Safety Basics

All varieties ship frozen and are meant to be thawed and eaten without reheating. Brand directions call for thawing at room temp for 30–60 minutes. Eat within 8–10 hours after thawing for the best texture. You can refrigerate a thawed sandwich for up to 24 hours, but the bread can dry out. Don’t refreeze thawed sandwiches or microwave them.

Thawing And Storage At A Glance

Action	Time/Window	Notes
Thaw at room temp	30–60 minutes	Keep in wrapper; no heating needed
Best-by eating window	8–10 hours post-thaw	Bread stays soft in this window
Refrigerate after thaw	Up to 24 hours	Bread can dry out in the fridge
Refreeze after thaw	Not advised	Quality drops; label says no
Microwave	Not advised	Hot filling risk; label says no

Calorie Math: What Changes The Count

Size Changes Everything

Move from 58 g to 76–80 g and you add 90–110 calories. That delta is normal math for extra bread and filling. If you’re budgeting energy tightly, stick to the smaller unit and build the rest of the meal with produce and lean protein.

Bread And Filling Choices

Wheat bread versions add fiber. Reduced sugar lines drop total sugars by a few grams per sandwich. Those shifts nudge calories and macros but don’t overhaul the profile. Taste and texture still read as PB&J.

Add-Ons And Tweaks

Some folks like to toast the edges, add banana slices, or drizzle honey. Those extras stack calories fast. If you want a higher-protein bite, pair the sandwich with milk or Greek yogurt rather than spreading extra peanut butter inside.

Label Notes And Sourcing

Here are the exact label sources used in this guide. The 210-calorie figure for the classic grape PB&J comes from the brand’s grape product page. The 210-calorie strawberry entry comes from its strawberry page. Reduced sugar wheat strawberry and grape both list 190 calories per 58 g. The 300-calorie figure for the 2.6 oz school unit comes from the K-12 case page. The 320-calorie figure for the 2.8 oz club pack appears on warehouse product listings. For broader nutrition context on PB&J sandwiches, you can search the USDA FoodData Central database.

Make It Work For Your Goals

If weight loss is the target, use the 190-calorie reduced sugar option at lunch with a crunchy salad. If you’re fueling a training day, the 210-calorie classic makes an easy pre-lift carb source. Parents packing for kids can match size to age and activity.
