The Size Tome increases the overall size of your attacks and projectiles in Megabonk. This makes your weapons and abilities cover more area, making it easier to land hits and control space. Since it is unlocked from the start, it is a useful Tome for almost every build.
Overview
- Stat: Size (Attack & Projectile Size)
- Per-level increase: Community testing suggests ~+10% per level (v1.0.7 era; not officially published)
- How to unlock: Default (available at start)
- Tome level cap: Community reports suggest high cap (possibly ~99), but not officially confirmed
Size is one of the most universally beneficial stats in Megabonk. Bigger hitboxes mean easier hits, better area coverage, and more consistent damage output. It's particularly valuable for characters and weapons with area-of-effect capabilities.
How Size Scales
Based on community technical analysis, Size appears to work as follows:
- Effective Size = Weapon Size à Character Size
- Character Size = Initial à (1 + Tome Size + Shrine Size)
- Size from Tomes and Shrines adds together (additive within character layer)
- The combined character Size then multiplies with weapon base Size
- Each Tome level adds approximately +10% to character Size (community-tested, not official)

Illustrative Size Progression
If we assume ~+10% per level (community estimate), here's how attack coverage might scale:
Important: These are illustrative approximations based on community-reported +10%/level. Exact values may vary by patch and are not officially documented. Always verify via in-game UI tooltips.
Size Comparison
Visualizing the difference in attack coverage:
Impact: Larger hitboxes mean more enemies hit per attack, easier aim requirements, and better crowd control. The difference is immediately noticeable and scales continuously.
Effects
- Increases the size of all attacks, projectiles, and AoE effects
- Makes hitting enemies easier, especially with slower or clunkier weapons
- Larger hitboxes help clear groups more efficiently
- Improves effective range for melee weapons
- Enhances area denial and battlefield control
How to Unlock
This Tome is available from the start of the game. No special condition is needed.
Weapon Effectiveness
Size benefits different weapon types to varying degrees. Examples based on verified weapon compatibility:
AoE, explosion, and lingering attack weapons gain massive value from Size increases:
Standard projectiles and melee attacks - significant improvement in hit consistency and coverage. Examples: Bow, Sword, Hammer, and most projectile-based weapons.
Hitscan, beam, and very fast projectile weapons - still beneficial but less impactful since they already have high accuracy. Examples: Laser weapons, instant-hit guns.
Note: Weapon names and compatibility verified via community weapon databases (TheGamer, GameRant, Fandom Wiki, 2025 Oct).
Common Tome Pairings
These are subjective gameplay suggestions based on community experience. Effectiveness varies by build and playstyle:
Strategy Guide
- Great for beginners because it makes aiming less precise and more forgiving
- Almost universally useful across all builds and weapon types
- Particularly strong with AoE and explosion-based weapons
- Improves melee weapon safety by extending effective reach
- Scales well throughout the entire game from early to late stages
- Consider investing early for immediate quality-of-life improvements
Best Use Cases
- New players - Forgiving hitboxes make the game more accessible
- AoE builds - Maximize area coverage and crowd control potential
- Melee characters - Extended reach increases safety and effectiveness
- High enemy density scenarios - More enemies per hit means exponential value
- Slow projectile weapons - Larger hitboxes compensate for travel time
- Screen-clear builds - Dominate entire areas with massive attack coverage
Tips & Considerations
- Considered one of the most universally useful Tomes by the community
- Very large hitboxes can sometimes cause visual clutter, but benefits typically outweigh drawbacks
- Particularly effective when combined with piercing projectiles (hit more targets per shot)
- Essential for "lazy" or "AFK" builds that prioritize passive damage and coverage
- Size increases from this Tome multiply with weapon base Size (based on community formula analysis)
- Works well with weapons that have persistent or lingering effects
Version & Patch Notes
Recent Size-Related Changes:
- v1.0.12 (Oct 2025): Black Hole default size increased by +20%, improving its base area coverage
- v1.0.17 (Oct 2025): Fixed issue where Hero Sword and Corrupted Sword projectile speeds weren't scaling correctly with very high Size values
- General Note: Tome values and mechanics can change between patches. Community-tested values (~+10%/level) are from v1.0.7 era
- Always verify: Check in-game UI tooltips for current patch values and mechanics
