They are both. Most tornadoes are no more than a few hundred feet wide, but a handful have been recorded at over 2 miles wide. This may seem huge by most human standards, but by weather standards it is small.
yes, some tornadoes are relatively small while others are huge
No. Hurricanes and tornadoes are two different types of storm. Size is not the only difference.

Of course tornadoes have been seen. They're not invisible. in fact, they're huge. You can see videos of tornadoes if you do a YouTube search.
When tornadoes are approaching they look like huge funnels. Tornadoes can approach an area very quickly You are advised to leave an hour before you can see the storm.
Generally, small tornadoes do less damage than large ones, but some small tornadoes have been very destructive.
How "small" &How "huge"
Strength is determined by wind speed, not size, in tornadoes. The Enhanced Fujita Scale categorizes tornadoes based on their estimated wind speeds and resulting damage. Tornado size can vary, with larger tornadoes usually associated with stronger wind speeds.
Yes, all tornadoes are dangerous. Some relatively small tornadoes have reach F4 or F5 intensity and caused catastrophic damage. Even weak tornadoes can cause major damage to trailer parks.
No. The weight of the cloud is not what forms the tornado. Tornadoes are form by interactions of wind currents within a thunderstorm.
HUGE or small HUGE or small
Not real tornado. Scientists have produces small vortices in labs that resemble tornadoes, and have simulated tornadoes in supercomputers, but they cannot create real tornadoes.
