When choosing a lighting fixture, getting the size and scale right is one of the most challenging aspects for people. Without expertise, it's difficult to determine the appropriate size for each area of the home that enhances its beauty.

guide to choose the right size lighting fixture

As a result, some fixtures may appear oversized or get lost in the space, failing to create a focal point. This article from Rowabi provides a pendant light size guide to help individuals answer the question "How big of a light fixture do I need?" in detail and clarity.

Factors to consider when choosing light fixture sizes

Choosing the right and suitable light fixture depends on more than just personal preferences. There are five key factors to consider, including room size and scale, light fixture diameter relative to dining table size, ceiling height, spacing for multiple light fixtures, and the room’s purpose.

Room size and scale

The dimensions of the room play a crucial role in selecting the size of light fixtures. Simply put, you must choose fixtures that harmonize with the overall space. Choosing small fixtures in large rooms may result in them getting lost in the space, while selecting oversized fixtures in small rooms can overwhelm and dominate the area.

Additionally, consider both the furniture and architectural features of the room to choose light fixtures that integrate seamlessly with the overall aesthetic.

Light fixture diameter by dining table size

Certainly, lighting above the dining table is indispensable in our homes, where the family gathers for meals, isn't it? For such cases, there's a general guideline: choose a fixture with a diameter that is approximately one-half to two-thirds the width of the dining table. This ensures that the light adequately illuminates the entire surface of the table in the most natural way possible.

Ceiling height

Ceiling height is crucial and greatly influences the choice of suitable light fixtures. For instance, pendant lights often come with suspension cords, so the height of the ceiling affects how they are hung and how the light turns out in the room. Rooms with high ceilings can accommodate larger fixtures with more intricate details. In contrast, those with low ceilings should opt for lower-profile fixtures to avoid feeling cramped and to prevent any risk of bumping one's head when moving around.

Spacing for multiple light fixtures

Some spaces demand more than just one light fixture, excluding chandeliers. These areas often serve as gathering spots with high activity levels, such as kitchens, hallways, or living rooms. Therefore, multiple light fixtures are necessary. In such cases, it's crucial to consider the spacing between them when purchasing and selecting the appropriate type and quantity. They should be spaced evenly to ensure a balanced proportion for the entire room.

Purpose of the room

The purpose of a room is a significant hint in selecting the appropriate light fixture. For task-oriented spaces like kitchens and home offices, focused lighting is essential for efficient work and household tasks. Therefore, we recommend fixtures such as rattan pendant lights, glass lights, or linear fixtures for optimal performance. Conversely, rooms like bedrooms require soft lighting, for which fixtures like schoolhouse lights, which provide gentle and soothing illumination, are suitable choices.

Light fixture sizing basics

Certainly, we will have simple general principles to determine the appropriate size. Here, we have sizing basics for three types: a singular light fixture in a room, a light fixture above a dining table or kitchen island, and multiple fixtures over a table or island. These principles provide a foundation for selecting fixtures that suit the space and fulfill its lighting requirements effectively.

 For a singular light fixture in a room

For a singular light fixture in a room, it's crucial to consider the room's size and scale. The best approach is to choose a fixture that complements the room's dimensions without appearing disproportionately small or large.

A useful rule of thumb is to add the length and width of the room in feet, and the resulting number can be the diameter of your fixture in inches. For instance, a room that's 12 feet wide by 12 feet long could accommodate a light fixture with a diameter of around 24 inches.

For a light fixture above a dining table or kitchen island

For light fixtures above a dining table or kitchen island, it's essential to select a fixture that is wide enough and provides sufficient brightness. Our recommendation is to choose a fixture with a diameter that is approximately one-half to two-thirds the width of the surface it is placed above. This ensures adequate coverage and illumination for the area without overwhelming it.

 For multiple fixtures over a table or island

When installing multiple fixtures over a table or island, ensure they are evenly spaced along the length of the surface to achieve balanced lighting. Keep a distance of approximately 18 to 24 inches between each fixture. Adjust the height of the fixtures to align with the ceiling height and desired lighting effect, typically hanging them 30 to 36 inches above the tabletop or island surface.

Pendant light size guide

At each location, different measurements are required to determine the optimal distance and number of lights. Therefore, below, Rowabi has compiled and analyzed common lighting placement scenarios for further examination.

Chandeliers above the table

As a rule of thumb, the diameter of individual pendants should be approximately one-third of the width of the table. For instance, if your table measures 36 inches wide, aim for pendants with a diameter of around 12 inches each.

In the case of a cluster, ensure that the combined lengths of the pendants also total approximately one-third of the table's width. Hang the pendants at a height of approximately 30 to 36 inches above the tabletop for optimal illumination.

Chandeliers as ambient light

For ambient lighting fixtures, a simple formula can be used for measurement: add the length and width of the room (in inches) together to determine an appropriate fixture width. To select the height, multiply the room height by 2.5 or 3, resulting in a range from which you can choose chandelier heights.

Pendants for an island or table

For pendants above an island or table, measure the width or diameter of the surface and subtract 12 inches from that number. This is the maximum limit for the width or diameter of a hanging light fixture. However, you can scale down the maximum width slightly based on whether you prefer the fixture to appear larger or smaller.

Pendants for ambient lighting

Similar to chandeliers, to determine the ideal height for a chandelier, multiply the room's height by 2.5 and 3. For example, if the room has a 10-foot ceiling, the resulting range for chandelier heights would be between 25 and 30 inches.

Outdoor wall lighting and door fixtures

To ensure the right size for outdoor wall lighting and door fixtures, divide the front door's height by 3 (for a single lantern) and 4 (for 2 lanterns), then select fixtures measuring around one-third to one-fourth of the door's height. This maintains proportionality without making the fixtures appear disproportionately small or large.

Garage outdoor lighting

For optimal curb appeal, ensure your exterior garage lights measure one-third to one-quarter the height of your garage door. Calculate the specific fixture size by multiplying the door width by 0.25 for a single door or 0.33 for a double door. When installing multiple wall lanterns, each lantern's height should be about one-fourth the door's height, while a single lantern should be approximately one-third the door's height.

Ceiling-mounted outdoor lights

To accurately determine the size of ceiling-mounted outdoor lights, calculate the fixture's diameter range by multiplying the area's square footage by 0.5 to 1.5. For instance, for a 100-square-foot area, the recommended fixture diameter would fall between 50 to 150 inches.

Outdoor hanging light fixtures

For a front door with a hanging lantern, aim for the lantern's height to be roughly one-fifth of the door's height. Ensure to account for the additional length of the chain or stem when hanging the lantern, and ensure that the lantern does not hang lower than 7 feet from the ground, including the fixture, chain, and stem.

Outdoor post lighting

To accurately size outdoor post lighting, measure the outdoor post's height in feet and evaluate the area you wish to illuminate, typically measured in square feet. Multiply the square footage of the area by a factor between 1.5 to 2 to determine the recommended lumens needed for sufficient lighting.

Bedroom ceiling fans

To accurately size a bedroom ceiling fan, measure the room's length and width in feet, and then calculate the total square footage. Based on the room's square footage, choose a ceiling fan with an appropriate blade span, such as 29 to 36 inches for rooms up to 75 square feet or 54 inches or larger for rooms exceeding 225 square feet. This ensures optimal air circulation and comfort in the bedroom.

Ceiling fans for other rooms

Similar to the bedroom, to accurately size ceiling fans for other rooms, measure the room's length and width in feet to calculate the total square footage. Then, based on this measurement, choose a fan with an appropriate blade span, such as 29 to 36 inches for rooms up to 75 square feet or 54 inches or larger for rooms exceeding 225 square feet. Install the selected ceiling fan, ensuring proper clearance for optimal air circulation and comfort throughout the room.

Foyer lighting Selection

For precise foyer lighting selection, ensure that the chandelier or pendant's height is proportional to the ceiling height. Aim for 2-3 inches of fixture height for each foot of ceiling height. Similarly, a two-story foyer can accommodate a larger chandelier or pendant ranging from 32 to 48 inches in height. This ensures aesthetic balance and proportionality.

Sconces for bathroom vanity lighting

For bathroom vanity lighting with sconces, mount them precisely at 65 inches above the finished floor, aligning the bottom edges of shades slightly below eye level to minimize glare. Place the sconces precisely 36 to 40 inches apart, flanking the mirror, with a distance of 18 inches from the sink's center line.

the right way to put sconces in bathroom vanity lighting

One small tip: opt for sconces of 12 inches or less for smaller bathrooms and sconces around 18 inches tall for average-sized bathrooms, while larger bathrooms can accommodate sconces measuring 19 inches or taller.

Sconces along staircases

For placement of sconces along staircases, measure the ceiling height in inches and multiply it by 3/4, as sconces are typically positioned three-quarters of the way up the wall. For example, with 8-foot (96-inch) ceilings, sconces would ideally be placed around 6 feet or 72 inches up.

Tips for choosing the best light for your style

Each style has particularly suitable lights that accentuate its beauty. Below are some typical styles for you to consider and choose from, including mid-century modern, modern, traditional, farmhouse, and coastal lighting.

Mid-century modern lighting

During the mid-20th century, we witnessed the emergence of numerous iconic designs. They were elegant and groundbreaking, yet still clean, simple, and timeless. Designs focused on functionality while maintaining a tidy appearance, emphasizing meticulous attention to detail.

This style often utilizes materials such as wood, metal, and glass, combining textures and finishes to create refined lighting. Brass, walnut, and frosted glass are commonly associated with mid-century modern lighting. For pendant lights, opt for designs with globe-shaped shades or, preferably, teardrop shades.

Modern lighting

With the primary principle of "less is more," modern lights typically feature clean lines and minimal ornamentation. For busy modern individuals, prioritizing functionality in their homes is paramount.

Lighting with sleek metal finishes such as brushed nickel, chrome, or matte black brings a minimalist, functional beauty that is understated and unobtrusive. Its highlight lies precisely in how it seamlessly blends with its surroundings.

Traditional lighting

Traditional lighting is characterized by its refinement, sophistication, and ability to showcase the enduring presence of these fixtures over time. This is because classic design is often accompanied by subtle intricacies that reveal their beauty and essence upon closer inspection.

These lights, whether chandeliers or lamps, typically utilize timeless materials such as crystal and glass. Fabric shades used in lamps often feature patterns like damask, toile, or floral motifs. All of these elements combine to create a gentle, warm, and nostalgic ambiance.

Coastal lighting

As summer approaches, the coastal style is set to reign supreme with its refreshing and relaxed vibe reminiscent of cool sea breezes. Coastal lighting embodies this aesthetic with grace and ease. Materials such as rattan, rope, and driftwood perfectly capture the essence of coastal living.

Pendant lights crafted from woven materials, ranging from minimalistic to uniquely intricate designs, bring a fresh seaside charm to any space.

Rattan, in particular, has emerged as a favored material in recent years. Its affordability, versatility in shaping, and durability make it a practical yet fashionable choice for coastal-inspired decor.

Farmhouse lighting

The farmhouse style truly embodies timeless lighting, as it evokes feelings of warmth, familiarity, and tranquility. It creates a sense of being in a peaceful area where one can immerse oneself in nature, simplicity, and relaxation.

Therefore, farmhouse lighting fixtures exude a similar vibe, such as mason jar or lantern-style shades. They can also feature rustic elements like distressed finishes, wrought iron, and reclaimed materials. Additionally, farmhouse lighting can be combined with industrial style by incorporating exposed bulbs, wire cages, and metal accents.

Design tips for selecting light fixtures

Here are some tips that Rowabi has consistently used to select the most stunning light fixtures for clients, which will be revealed below.

Maintain balance

Balance is a concept frequently emphasized in both interior design in general and lighting design in particular. Here, balance refers to the proportional relationship between each object within a room.

Each object has its own proportion that harmonizes with and enhances the overall composition. In this case, an appropriate light fixture typically occupies around one-third of the width of the entire room, ensuring that smaller spaces are not overwhelmed by overly large fixtures and larger rooms do not feel cramped with tiny ones.

Consider style and function

No matter how much you may like a particular light fixture, if it doesn't complement the overall style of the home or serve its intended purpose effectively, it's best to exclude it from consideration and explore other options.

Each room will require a specific type of lighting, categorized as accent, ambient, or task lighting. Therefore, it's essential to determine the purpose and intent of the lighting from the outset to make a careful selection.

Try layered lighting

Layering is a suitable method for those seeking to make a room versatile and multifaceted. This means that within a room, there should be sections where ambient lighting is crucial to create a shared space for the whole household.

However, there are also areas where accent or task lighting is desired to focus on specific zones. By combining these layers, you can create a flexible lighting scheme that addresses different needs and moods.

Don’t be afraid of size

While we've discussed the established principles for selecting the most suitable light fixtures, if you're inclined towards innovation, seeking to completely transform the look of a room, and expressing your personality, oversized fixtures might be a perfect fit. However, careful consideration and possibly seeking advice from professionals are necessary to choose the most suitable one.
