In this complete guide, we’ll explore the factors that determine butternut squash size, provide a size chart from mini to giant varieties, and share tips for growing large, healthy fruits. Read on to learn all about butternut squash sizes!
Typical Butternut Squash Sizes
Most standard butternut squash varieties reach sizes between 2 to 5 pounds when fully ripe. The average length at maturity is about 12 inches.
Within this range, a small butternut is around 2 pounds and 6-8 inches long. Medium squash hit 3-4 pounds and get up to 10 inches long. Large types max out around 5 pounds and 12 inches in length
These sizes are perfect for 1-2 person servings. The smaller squash make great single portion sides when roasted or baked into recipes.
What Impacts Butternut Squash Size?
Several key factors influence the final size butternut squash reach:
-
Cultivar – Some varieties are bred to stay small, while others produce extra-large fruits. Selecting the right cultivar for your target size is crucial.
-
Growing conditions – Factors like sunlight, soil nutrition, and water impact size. Optimal conditions promote maximum growth.
-
Harvest timing – Picking early yields smaller squash than waiting until completely mature.
-
Pests/diseases – Issues like powdery mildew stunt growth if not promptly treated.
Gardeners can optimize squash size by selecting an appropriate cultivar and providing ideal growing conditions. Timely harvesting at peak maturity also ensures the largest fruits.
Mini and Small Butternut Varieties
For small space gardens, there are bush-type butternut varieties that produce petite squash. These compact plants spread less and are great for containers.
Some top small butternut cultivars include:
- Honey Bear – 3 lb fruits on bushy vines perfect for pots
- Early Butternut – 4 lb heirlooms; fast maturing
- Butterscotch – 1-2 lb personal-sized; All-America Selections winner
- Bugle – 3 lb uniform squash on semi-bush plants
With these, expect fruits around 4-8 inches long when mature. The flesh has full butternut flavor despite the smaller size.
Average Butternut Squash Sizes
Most butternut varieties yield medium 3-5 pound fruits when grown under ideal conditions and harvested at peak ripeness. Some examples:
- Waltham – 4 lb average; heirloom; All-America Selections winner
- Hunter – 5 lb uniform orange fruits; semi-bush habit
- Metro PMR – Disease-resistant; 4-5 lb fruits
- Burpee’s Bush Table Queen – 3-5 lb average; compact vines
These produce the classic 10 inch long by 5 inch wide butternut shape. The size provides 2-4 portions for recipes.
Large and Giant Butternut Varieties
Some butternut cultivars have been bred to bear extra-large fruits for higher yields. Giant types average 8-15 pounds!
A few jumbo varieties to look for:
- JWS 6823 PMR – 10 lb average; powdery mildew resistant
- Atlas – 15 lb fruits; All-America Selections winner
- Zenith – 10 lb uniform dark orange squash
- Magnum – 8-10 lb average; semi-bush habit
These fruits measure 12-18 inches long – great for large families, contests, and displays.
Ideal Conditions for Maximum Size
To encourage your butternut squash to reach its full potential, provide ideal growing conditions:
- Full sun – At least 6 hours of direct sun daily
- Fertilize regularly – Use compost tea or organic balanced fertilizer
- Water deeply – Supply 1-2 inches weekly; avoid drought stress
- Give adequate spacing – Allow room for vines to spread
- Control pests & diseases – Treat issues ASAP to prevent stunted growth
- Harvest at maturity – Wait for deep tan rind with no green streaks
Meeting the variety’s needs for sunlight, nutrition, moisture, and space ensures proper fruit development to maximum size.
Harvest Timing Affects Size
Butternut squash sizes vary greatly depending on harvest time. Picking early means smaller fruits versus waiting until completely ripe.
- Immature – Harvested too soon; pale tan rind with green; lower yields
- Peak – Harvested when mature; deep tan rind; maximum size
- Overmature – Left on vine too long; rind hardens and fruits shrivel
For the biggest butternut squash, time the harvest precisely at peak maturity. Don’t pick early or leave ripe ones to linger too long.

BEST TO START OUTDOORS
Honey Nuts need full sun, rich fertile soil and warm temperatures. Wait to plant until nights are comfortably above 50°F (10°C) both day and night. Sow groups of 2 to 3 seeds 2 ft. apart and 1 in. deep in rows 4 ft. apart. Thin to 1 strong seedling per group to give vines room to ramble or climb. Or make slightly mounded hills 2 to 3 ft. across and 6 ft. apart and plant 4 to 5 seeds in each hill. When seedlings have several sets of leaves, thin to the strongest 3 seedlings per hill.
Protect young seedlings from marauding birds by covering with plastic berry baskets at sowing time, removing before plants get crowded. To save space, and make picking easy, Honey Nut vines can easily be trained up fences, trellises or 4-6 foot tall teepees.
