Setting is an important part of any story of any length. Stories involve action and action needs some place to happen. That’s the setting. Setting has to involve more than just one sense. There may not be a breeze in the location where your action takes place, but there should be air. There should be temperature. There’s a world of difference between sitting and talking at a kitchen table and sitting in a living room or family room. Make your readers see the place in their mind’s eye. Make them feel the temperature of the room.
That said, you shouldn’t go heavily into the description to the point that it overpowers the action. Like everything in writing, there must be balance. You don’t want the action taking place in a vacuum, but you don’t want to bore your reader with too much description. Settings are the backdrop. A play would not be as good if there was no scenery, minimal or not. The written page even more so. A small touch here and there would be sufficient.
John stood before the fire, warming his hands, reveling in chasing the chill from his bones. A slight step behind him made him turn to see a baseball bat heading for his head.
You may not know where John is, but you know several things. One, it’s a chilly day. Two, he’s indoors and may have just entered. Third, someone apparently doesn’t like him. Let’s continue this.
The last thing John saw before he lost consciousness was the dust bunny next to the turned wood leg of the sofa.
You can see the thick dust under the sofa. Just add little touches and that paints a picture of the place a heavier description would never be able to match. Just a few details will break the action, but not by much.
Your setting should match the action. A high speed chase works better on crowded city streets than on a two lane highway in the middle of nowhere. There’s more room for things to go wrong. The reader can worry about the passers-by or the pursued or the pursuers, depending on who you have chasing who. Likewise, you wouldn’t have a peaceful fishing expedition on an interstate.
Describe your setting carefully. I often describe mine in a paragraph in the story notes. That allows me to visualize it before I add in any action. That’s more useful for town, houses and rooms, though. Describe them in minute detail in your notes. Then you can use those notes to intersperse a sentence here and there to describe it for your readers. Do that and you will find it easier to balance action and description.
